I honestly haven't run into any programs that use the "Album Artists" tag before, but that does seem like a potentially ideal solution. Sadly I don't see myself going back to edit thousands of albums.
Regrettably Album Artists is not a common tag, and even for MusicBee you will have to create a custom tag for it before you can use it.
So you have thousands of albums that can be considered to have multiple album artists?
That's a lot!
Using combined values in the Album Artist tag just doesn't make sense to me honestly,...
Neither does it to me.
The 'album artist' for an album is usually artist intent, and should be respected in my opinion.
For example:
Eno & Hyde
Corea, Clarke & White
Rufus With Chaka Khan
Chet Baker Quartet Featuring Russ Freeman
If these individual artists were split up in a multi-value tag, how would one know anymore what the correct and original album artist for that album is?
Is there a specific thread I should post in for a request to have a $SortMulti function added? Not sure this falls under the Additional Tagging section but I could be wrong
Just post in the plugin's thread.
Boroda will see it there sooner or later.
Make sure to explain the purpose and/or paste a link to your post in this thread about it.
