I think Add 2 multi value tags. %album artist multi% and %artist multi% (anyway name of them must be editable in tag mappings) but name strings must be resolved to main MusicBrainz artist name or give option. This allow to give best advantages of MusicBrainz data, to have super correct navigation in library (like in MusicBrainz site). Because, now so many album artist have "artist1 meets/&/feat./etc artist2" and it's not good for navigating in large libraries. Also, if we use, only one tag for all (%album artist% and %artist%), then we can't get good navigation for main artist entires. In my library quantity of %artist% > ~70% then %album artist%. Also this features help autoplaylists maniacs.
