Yes, at a certain moment in time MusicBee started to allow 'Album Artist' to be multi-value.
Which was a bad decision in my opinion.
I disagree. Of course an album can have multiple album artists. I've just included two screenshots where that is the case.
The concept of having 'Album' and 'Album Artist' is essential to keep tracks belonging to an 'album' together.
When a user has no understanding of that and/or chooses to ignore that simple principle it can result in unforeseen issues.
(plenty of such issues have been discussed on the forum already)
If anything, it's usually people not being aware of the
Album Artist tag who ask why their compilation albums aren't shown as a single album. I can't recall many issues attributed to people using it incorrectly.
Assigning multiple values to the
Album Artist tag has no bearing on how albums are grouped in MusicBee that I've seen. Quite the opposite - where it's appropriate to add multiple artists, MusicBee handles it well and it makes it easier to find collaborative albums. As I've shown above, for that soundtrack album, I can browse to the entry for either Trent Reznor or Atticus Ross in the
Thumbnail Browser and
Column Browser and the album appears under both, exactly as I'd expect it to.
I'm not sure what you've done in the past. Maybe earlier implementations had issues which have since been fixed, or you tried to do something funky with it, but it's been working fine for me for years. Given MusicBee's practically infinite combination of possible layout permutations , I'm sure there are ways to break different views if you try, but the same can be said for any tag.
In my opinion it wouldn't be a bad thing if MusicBee would revert to 'Album Artist' only being allowed to be a single-value tag.
That's a big call. It makes sense for
Album Artist to allow multiple values to reflect the fact that many album do in fact have multiple artists.
And you haven't actually presented a case for where it doesn't work as you'd expect it to.
'Album' is not allowed to be multi-value either, is it? (I haven't checked, but I hope not)
This isn't comparing like for like - A single track/file
can't belong to multiple albums. An album
can have multiple artists.
(And it is possible to add multiple
Album tags to a file using the Tag Inspector, but MusicBee doesn't really try to handle it. I would describe the results as 'undefined'.)
Users having an understanding of the matter, and a good reason to use a multi-value 'Album Artist' can easily establish that by creating a custom tag for 'Album Artists'. I am doing that myself.
I'm not sure you're gaining anything by doing that. It would depend on your own settings of course, but it sounds like your custom
Album Artists tag just replicates what MusicBee would do with the normal
Album Artist tag.
