I also already considered how multiple artists could be enabled.
So to be clear we are talking about two distinct tags (ot frames): AlbumArtist and Artist
While AlbumArtist is supposed to have only one single value (as far as interpret the standards),
there may be multiple Artists for a track.
All tags are per track, i.e., there is no "Album" entity. Tracks having the same Album tag are considered to belong to the same album. Theoretically tracks with a common album tag can as well have different AlbumArtist tags. But in Moode, as far as I read the code correctly, albums are identified by a combination of Album+AlbumArtist. So tracks with the same album tag but different albumartist tags are displayed as two distinct albums.
To make things even more complicated, I found tracks with multiple AlbumArtist tags. Some editors allow for adding tags/frames ad libidum and music databases like mpd can also handle this situation.
So as to me, best practice is probably to use one single AlbumArtist tag value with entries of either "Various Artists" or a string of the form "Artist A & Artist B ...".
Now to the Artist tag. In contrast to the AlbumArtist tag it can have one or multiple values (or to be precise: there can be multiple artist frames per track).
Currently Moode supports only one Artist tag per track. It is displayed with each track when showing the list of tracks for an album or in the player queue. The Artist tag is also used as a substitute when the AlbumArtist tag is missing.
I think there might be room for improvement.
Conclusion:
-- AlbumArtist should have only one value per albun
-- Artist can have multiple values. But we have to think twice on how these may be displayed in tracks view w/o littering the view and what to use as a substitute for a missing AlbumArtist tag in order to uniquely identify an album.
