I believe to have read somewhere that when entering classical music in MusicBrainz, a ‘work type’ can be entered.
For example ‘Concerto’, ‘Opera’, ‘Symphony’, etc.
But checking out a couple of albums on MusicBrainz where I would expect such info present, I haven’t been able to find it showing up anywhere.
Also at trying out Picard on a couple of such works, I don’t see that field showing up in tags.
What am I missing here?
