Is there a iOS FLAC player that honours Musicbrainz album ids? The VOX app will fold two albums together if they have the same name. I would think a player that groups tracks together using Musicbrainz album ID metadata wouldn’t make that mistake.
Unlikely, but I’m surprised this would be necessary. Reasonable apps should define an album based on the combination of Album, Album Artist, and Date. (Maybe throw in Album Sort Order as well.)
Can you give us the names of the two albums and the artist for each?
