My perfect system

  • tracks have MBIDs.
  • recordings get merged a lot more than they do now.

I like the FRBR model, which in musicbrainz has a good mapping for albums, and I believe we should have the same mapping for songs:

FRBR MB album MB song
work work work
expression release group recording
manifestation release track
item ___ ___

So when recordings should be merged etc.. should follow Expression as defined in 3.2.2 at .


Currently tracks on my local disc have recording MBIDs (and artist, album artist and release MBIDs I guess). But those ids are not useful for identifying a particular file on disc, or linking other data to a particular file, because there are releases where I have different versions of the release, and thus have different files with the same recording MBID.

  • You just need to identify your files with {recording MBID + release MBID} Murdos (talk) 22:57, 19 December 2012 (UTC)
    • No, there are releases where a recording MBID appears on a release multiple times. --warp.
    • The current compound key to looking up a track is (release MBID, disc position, track position). This proposal would basically just replace that with a UUID. (This would fix issues with disc reordering; whether it help track reordering is less clear.) Kepstin (talk) 16:40, 20 December 2012 (UTC)

I could ofcourse assign my own id or just use filename + path, but then I cannot communicate with other systems about this music. So, I want track ids again.
