| INTRODUCTION                                                                  |
| After half a year and with ruleset wording misinterpretations, it is time to  |
| revise and add some rules.                                                    |
|                                                                               |
| NOTE: The definitions of these keywords are to be interpreted as follows:     |
|       MUST=obligatory (release not allowed if rule not followed)              |
|       SHOULD=suggested (release allowed if not followed)                      |
|       CAN+MAY=optional (release allowed if not followed)                      |
|                                                                               |
|       Unless clearly stated in a specific rule or note, capitalization in this|
|       ruleset is considered as informative.                                   |
+-------------------------------------------------------------------------------+
| GENERAL                                                                       |
|  1.1 A release MUST contain an SFV, NFO, and JPG proof.                       |
|      .1 A release MAY contain other relevant JPG files.                       |
|      .2 A release MAY contain CUE and LOG files if it is from a CD source.    |
|      .3 Valid filetypes are: .cue, .flac, .jpg, .log, .m3u, .nfo and .sfv.    |
|  1.2 Valid media sources are: BLURAY, CD, DVD, HDDVD and VINYL.               |
|      .1 A release MUST not mix sources.                                       |
|  1.3 Trackfixes are not allowed, bad quality rips require a complete repack   |
|      and MUST include ADDITIONAL type tag: -REPACK- or -RERIP- (rule 4.6).    |
|  1.4 The following are reasons for a bad quality rip:                         |
|      .1 One or more tracks from the release are incomplete or contain skips.  |
|      .2 The tracks are distorted and constantly clipping (eg. vinyl rips).    |
|      .3 The tracks contain a constant hiss which was avoidable (eg. vinyl     |
|         rips).                                                                |
|      .4 Low sound, mono rips (from stereo sources) and other factors easily   |
|         heard by the human ear.                                               |
|  1.5 The maximum directory and filename length is 128 characters. Directories |
|      and filenames must only contain valid characters: a-z A-Z 0-9 _ . - ()   |
|  1.6 All CD releases (including mixed CD's / e.g. DJ-Mixes) MUST be ripped    |
|      as separated tracks according to the TOC (Table Of Contents) on the CD.  |
|      The only occasion where a CD is released as one single track is when     |
|      there is only one track on the CD.                                       |
|  NOTE: Lossless data compression excludes the possibility of the introduction |
|      of padding, all lossless audio file formats are inherently gapless.      |
+-------------------------------------------------------------------------------+
| DUPES                                                                         |
|  2.1 A release MUST include all audio tracks. Releasing just the bonus tracks |
|      or some other subset of tracks is not allowed. Similarly, a BONUS DISC   |
|      cannot be released by itself, but must be released as a complete release.|
|  2.2 A release MUST not be identical to a previous release, except            |
|      ADVANCE/PROMO releases (Rule 7.2).                                       |
|  2.3 A release is not identical to a previous release if:                     |
|      .1 The previous version has a different mastering.                       |
|      .2 The previous version has a different tracklist.                       |
|      .3 The previous version has a different version of a track.              |
|  2.4 A release MUST not be a collection of discs that have already all been   |
|      individually released. For example, releasing a 2CD that combines a      |
|      CD and EP after they have both been indivually released is not allowed.  |
|      Likewise, a boxset of albums cannot be released if each album has        |
|      already been indivually released.                                        |
|  2.5 A release MUST not have all its tracks included in one previous release. |
|      Examples: a CDS cannot be released after a CDM that includes all the     |
|      tracks on the CDS. An album cannot be released after a boxset that       |
|      includes all the tracks from that same album. A CDM or EP cannot be      |
|      released after a release has been reissued with all tracks.              |
|  2.6 All sources MUST follow the above dupe rules as well as the following    |
|      source specific rules:                                                   |
|       .1 BLURAY can dupe any other source, except HDDVD.                      |
|       .2 HDDVD can dupe any other source, except BLURAY.                      |
|       .3 CD can dupe any other source, except BLURAY and HDDVD.               |
|       .4 DVD cannot dupe any other source.                                    |
|       .5 VINYL cannot dupe any other source.                                  |

|      .2 Channels, Bits per Sample and Sample Frequency, must be kept.         |
|      .3 A DVD release must contain all music tracks. Additional tracks (clips,|

|         only) is not allowed.                                                 |
|      .4 The nfo file MUST contain the following source information:           |
|         - Codec (LPCM)                                                        |
|         - Bitrate (640kbps, 768kbps, 1536kbps...)                             |
|         - Number of channels (Stereo, 5.1, ...)                               |
|  3.4 HDDVD/BLURAY encoding:                                                   |
|      .1 Highest audio source must be used.                                    |
|      .2 Channels, Bits per Sample and Sample Frequency, must be kept.         |
|      .3 Audio source choice priority from highest bitrate is:                 |
|         - DTS-HD Master Audio                                                 |
|         - Dolby TrueHD                                                        |
|         - LPCM                                                                |
|      .4 HDDVD/BLURAY video clip releases should be ripped as multiple tracks, |
|         (eg: like any regular Compilation CD release).                        |
|      .5 HDDVD/BLURAY releases with multiple files, but all belonging to the   |
|         same playlist index, must be encoded together in the same order the   |
|         playlist index file indicates.                                        |

|  4.1 The tag -FLAC- MUST be in uppercase in the release name and always       |
|      before -YEAR- and -GROUP tags.                                           |

|         If not possible to identify, the word "Unknown" can be used.          |
|         Compilations (eg: Soundtracks, Samplers) with various artists must use|

|      tracklist usually occurs with specific presses, at different countries,  |
|      with different artists or different/more tracks for the same release     |
|      title. Different year reports to reissue releases (refer to rule 4.10).  |
|      Some releases need to be identified from the normal ones due to their    |
|      source nature. (eg: soundtrack compilation, magazine bonus CD, etc).     |
|      Therefore valid allowed TYPE tags are:                                   |
|      - Advance, Promo, Retail, Bonus                                          |

|      - Clean, Explicit                                                        |
|      .1 TYPE can be a combination of the keywords featured in rule 4.5 using  |
|        the _ (underscore) space replacement. (eg. -Reissue_Limited_Edition-). |
|  4.6 Valid ADDITIONAL tags: (Uppercase MUST be used)                          |
|      - DIRFIX, NFOFIX, PROPER, READNFO, REPACK, RERIP, REAL and CUEFIX.       |
|      .1 If an ADDITIONAL tag is used, the nfo MUST mention the release name   |
|         that it is replacing or updating.                                     |
|      .2 DIRFIX and NFOFIX are exempt from Rule 1.1.                           |
|  4.7 LANGUAGE (LANG) must follow the ccTLD identifiers (2-chars):             |
|      (Capitalized letters MUST be used)                                       |
|      http://www.iana.org/domains/root/db/                                     |
|  4.8 Mandatory release name formats:                                          |
|      - Artist-Title-SOURCE-FLAC-YEAR-GROUP                                    |
|      - Artist-Title-LANG-SOURCE-FLAC-YEAR-GROUP                               |

|      - Artist-Title-(CATALOGUE)-LANG-ADDITIONAL-TYPE-SOURCE-FLAC-YEAR-GROUP   |
|  4.8.1 Any spaces in ARTIST and TITLE should be replaced with _ (underscore). |
|        If ARTIST or TITLE has . (dots) or - (dash), it is encouraged to be    |
|        kept as close as they appear on the cover/booklet/physical medium,     |
|        but they do not have to be nuked if not.                               |
|  4.9 .1 Internal releases must be tagged GRP_iNT or GRP_INT.                  |

| 4.10 YEAR tag must be the year when the record company/artist published it.   |
|      For non original presses, the additional TYPE tagging MUST be applied.   |
|      (example: release originally released in 1990, but rip is from 2000      |
|      reissue, correct year would be 2000, with additional TYPE tagging).      |
| 4.11 LANGUAGE tag is MANDATORY for non english releases.                      |
|      If the vocals are non-english and the majority of them are best described|
|      using one TLD country code abbreviation, then the most appropriate       |
|      TLD SHOULD be chosen and MUST be used as a tag in the release name.      |
| 4.12 Typos in releases where the TITLE and/or ARTIST name are in English ARE  |
|      NOT TOLERATED. The ADDITIONAL tag, DIRFIX must be used to fix a release  |
|      name typo (ref to rule 4.6).                                             |
|      .1 ARTIST and/or TITLE must not be translated to English from their      |
|         native language. English alphabet characters must be used to reflect  |
|         artist and/or title names (ref to rule 1.5).                          |
|                                                                               |
| NOTE:                                                                         |
|  - CATALOGUE and TYPE are optional tags (except for Rule 4.10). When they are |
|    used, they must be placed in the correct order.                            |

|  5.2 All filenames (including SFV, NFO, JPG) MUST be lowercase.               |
|  5.3 Track titles must be exactly the same as written on the backcover        |
|      tracklist containing all additional infos like featured artists or       |
|      remixers, if they are present, as long it does not exceed the maximum    |
|      filename length (see rule 1.5).                                          |
|      If additional information is shown at lyrics titles, inlay or cd         |
|      listing, it is encouraged to write them aswell.                          |
|      NOTE: Typos are tolerated as long as they do not compromise the          |
|            readability of file names. If tracklist has changes, due to press  |
|            errors for example, it is encouraged to explain them in the .nfo   |
|  5.4 Recommended filename formats:                                            |
|      - nr-artist-title.flac                                                   |
|      - nr-artist-title_(remixer_or_featured_artist).flac                      |
|      - a1-artist-title.flac                                                   |
|      - b2-artist-title.flac                                                   |
|  5.5 Including -groupname in the filenames is allowed but not recommended.    |
|  5.6 Repacked or reripped releases MUST include a -repack or -rerip suffix on |
|      each .flac file.                                                         |
|  5.7 In VA releases actual artist name MUST be before song title. VA (Various |
|      Artists) is not a valid artist (01-va-song_title is unacceptable).       |
+-------------------------------------------------------------------------------+
| VORBIS TAGS                                                                   |
|  6.1 FLAC files MUST only contain Vorbis comments and Vorbis comment field    |
|      names must be unique. For example, a FLAC file MUST not have two ARTIST  |
|      field names even though the specification supports this.                 |
|  6.2 All FLAC files MUST have the following Vorbis comment field names and    |
|      corresponding field contents: TRACKNUMBER, ARTIST, TITLE, ALBUM, GENRE,  |
|      and DATE (format: YYYY).                                                 |
|      .1 All FLAC files SHOULD also have the following Vorbis comment field    |
|         names and corresponding field contents: TOTALTRACKS, DISCNUMBER and   |
|         TOTALDISCS.                                                           |
|      .2 The "vendor_string" field of the VORBIS_COMMENT metadata block MUST   |
|         be present indicating the correct lib FLAC version. Be aware that some|
|         software removes this field by default.                               |
|      .3 For VA releases the ARTIST field contents MUST have the corresponding |
|         artist name not "VA".                                                 |
|  6.3 The FLAC picture block (METADATA_BLOCK_PICTURE) must be empty. Any cover |
|      or booklet scans MUST follow Rule 9.5                                    |
|  6.4 Vorbis comment field contents use UTF-8 character encoding to allow easy |
|      representation of any language. It is recommended to use UTF-8 in field  |
|      contents to ensure accurate tagging. Filenames MUST follow Rule 1.5.     |
|  6.5 The GENRE field content MUST be the same for all the files in a release  |
|      and it MUST be one of the genres listed in the id3 specification list:   |
|      http://www.id3.org/id3v2.3.0#line-1089 and the additional nullsoft       |
|      genres index number 125 onwards. namely:                                 |
|      Goa, Drum & Bass, Club House, Hardcore, Terror, Indie, BritPop,          |
|      Negerpunk, Polsk Punk, Beat, Christian Gangsta Rap, Heavy Metal,         |
|      Black Metal, Crossover, Contemporary Christian, Christian Rock,          |
|      Merengue, Salsa, Thrash Metal, Anime, JPop, Synthpop, Unknown.           |
|      NOTE: The genre "Psychadelic" was originally misspelled in the list and  |
|            therefore using the correct spelling of "Psychedelic" is not a     |
|            valid nuke reason. This typo was later fixed in the Nullsoft list. |

|  7.1 An ADVANCE or PROMO is not available at retail and is usually labeled    |
|      with some variation of the words Advance and/or Promotional. Having a    |
|      release before its retail date does not automatically make it an ADVANCE.|
|  7.2 ADVANCE and PROMO releases can always be duped by any retail release even|
|      if the tracks on both releases are identical.                            |
|  7.3 ADVANCE and PROMO releases with voice overs, silence, or cuts on tracks  |
|      are not allowed.                                                         |

|  8.1 A bootleg is a release or recording that was not officially released by  |
|      the artist or record company (unofficial / unlicensed recordings).       |
|  8.2 Conditions for bootleg releases are:                                     |
|      - There are no signs that the record company really released it.         |
|      - The artist or record company did not confirm the release as valid.     |
|      - The record company has no connection to the artist on the release.     |
|      - The record company does not exist and the release not self-released.   |
|      - The release is not available at at least three retail stores.          |
|  8.3 Currently valid retail stores (alphabetic order):                        |
|      - www.amazon.com                                                         |

|  NOTE: The shop itself must sell the record, no private sellers.              |
|  8.4 Due to their unofficial nature, bootlegs might carry audio defects       |
|      (ei. skips, glitches, etc). If these audio defects are identified at nfo |
|      then a release cannot be considered invalid until there is a valid one   |
|      (ei. proper release clean of audio defects).                             |

| PROOF                                                                         |
|  9.1 Releases must always contain a proof CAMERA picture in JPG format.       |
|  9.2 Proof camera pictures must contain both, medium and cover together.      |
|      If cover isnt possible, a booklet or promo sheet or anything valid       |
|      proving ripper has release. If the medium/cover/booklet contain anything |
|      that may expose your identity, then that part of image can be blurred or |
|      blackened.                                                               |
|  9.3 The proof picture MUST include small piece of paper over medium and/or   |
|      cover with GRP name.                                                     |
|      Artist, title and any other relevant info that proves release, must not  |
|      be hidden behind the piece of paper.                                     |
|  9.4 GROUP tag must be photographed in the proof picture, software-edited     |
|      tags are considered invalid proof. Camera picture proof must not be      |
|      changed except to hide anything that might expose ripper (read Rule 9.2).|
|  9.5 Additional scans may be added but DO NOT count for proof.                |
|  9.6 Proof camera pictures resolution must be at least 640 width and 480      |
|      height in JPEG format.                                                   |
|      Artist and/or album/single title must be clearly readable.               |
|  9.7 Proof fixes are not allowed, missing proof picture or bad resolution     |
|      requires a complete repack.                                              |
| NOTE: EXIF metadata should be removed from JPEG files! Uniquely identifying   |
|       information such as the camera serial number and GPS coordinates can    |
|       pose a security threat if not removed, so this is very ESSENTIAL!       |
