[PROBLEM] Multiple Versions of Albums

[challenge]

Just for reference, here are the tags that MPD supports
https://www.musicpd.org/doc/html/protocol.html#tags

don't know the status of this, so pardon if already somehow fixed in last releases...

btw i'm talking about two releases of the same album, same title tag, same song title tags, different catalog number, different musicbrainz_albumid
i.e. different country release, or MFSL hd tracks editions.
As now moode sees them as duplicates songs and put them all together inside the same album. So I get duplicates of every song with same tags.
A quick and dirty solution was appending the catalog number to the album name tag, working but too messy.

now I understand mpd doesn't support catalog number...
-> what about adding a subroutine to the library view code to group albums by "musicbrainz_albumid" (="MusicBrainz Release Id" in mb picard) if not empty, but keeping the final sorting by year or title as you can set under Appearance.

It's supported by mpd, can already see it in track info, at least it would stop the duplicates.

Then as final touch it would be nice to expose the mpd comment tag, maybe on mouse-over the title or in the cover's drop-down menu. This way I could easily write the catalog number there, and would be able to distinguish them in library without cluttering the UI.
thanks
