=Track Groups=

*Instead of selecting a recording when adding a release, you select the work. The track is added to the work, which contains a long list of all associated tracks in some non-default tab.
*The list of tracks is arranged into track groups, which correspond to specific versions of the work. Track groups each have a corresponding artist and optionally a description.
*All works have a new field, called "original performer". This contains the artist(s) who originally performed the track. The system uses this field to designate some track groups as "covers".
*When a track is added to a work, it gets put into the default track group for the track artist. The default track group is probably where most tracks on compilations would end up.
*You can move a track between track groups, and make new track groups. A track group would be made for every significantly different version of a track. This includes notable remasters.
*Tracks in a group can have varying lengths. The length is unimportant, as long as the portion of audio that is in a track is the same as other audio in the group.

For example:

==Song - "Waterloo"==

*Type: Song
*Lyrics Language: English
*Original Performer: ABBA

===Track Group by ABBA===
*Track 1: 3:20 (from 1974 US vinyl "Ring Ring")
*Track 2: 3:20 (from 1974 Swedish vinyl "Ring Ring")
*Track 3: 3:01 (from 1999 CD "Best of the 70s")

===Track Group (single) by ABBA===
*Track 1: 2:32 (from 1975 Swedish single "Waterloo")

===Track Group "2001 Remaster" by ABBA===
*Track 1: 3:20 (from 2001 CD "Ring Ring")
*Track 2: 3:21 (from 2002 CD "ABBA: The Complete 2001 Remasters")

===Track Group (cover) by Bjorn Again===
*Track 1: 2:19 (from 1995 CD "Rung Rung")


----

There are no recordings here.

By default, "Waterloo" album tracks by ABBA will go in the top group, which is the default album track group. "Waterloo" tracks from singles by ABBA will go in the second group by default.

You can move tracks and merge tracks in edits after they've been added. Track groups can also be merged, created and split. In this case, the track group "2001 Remaster" by artist "ABBA" has been created by a user, and the two tracks in there have been moved there after they were added. Alternatively, there's an option when adding a release to put tracks in a specific group, to save editing afterwards, and to create a new group for the track. But these options are hidden by default.

The cover by Bjorn Again has its own group. This is the default group for the artist Bjorn Again, and all "Waterloo" tracks by Bjorn Again will go there. This group was automatically labelled cover, because the original performer is listed as ABBA.

=Introduction=
This proposal is designed to improve the guidelines on merging recordings. It is felt that the current guidelines are too vague, and that they don't cover all cases where recordings might be merged. This proposal seeks to expand these guidelines and make them clearer.

=Proposal=
Edit http://musicbrainz.org/doc/Style/Recording to change the section "What should and shouldn't be merged together?" to the following.

==What should and shouldn't share recordings?==
A recording is intended to represent distinct audio. This means that generally two tracks should only share a recording if the audio that they contain sounds the same. If it isn't clear whether to merge two recordings or not, keep them separate. Where two recordings of the same work are separate for a reason, a meaningful disambiguation should be provided for one or both of the recordings.

===Specific Cases===
#Tracks containing different performances of a single work should each use a separate recording, since each performance will result in distinct audio.
#Releases of live performances that are recorded by different recording devices should each use a separate set of recordings.
#Versions of a release that are mastered in audibly different ways should use separate recordings.
#If audio restoration is used to create remastered audio from an earlier recording, a track containing the remastered audio should use a recording specific to that remaster.
#A track containing edited or remixed audio should always use a recording specific to that particular edit or remix.
#Tracks which contain different numbers of audio channels should always use separate recordings. For example, a mono recording and a stereo recording should never be merged.
#If a track begins or ends in silence and a second track changes the length of the silence, but is otherwise identical, these two tracks should share a recording, so long as the silence isn't a significant part of the audio.

===AcoustIDs and ISRCs===
Both of these identifiers can be incorrectly attached to recordings. For this reason, neither AcoustIDs nor ISRCs should be used as the sole reason for merging two recordings. Different AcoustID fingerprints and ISRCs may be used as a reason for not merging, but bear in mind that they can sometimes be wrong.

Before attempting to work with AcoustIDs, please read the [[Guides/AcoustID|AcoustID Guide]].
