"Just seems to me in that case you could set album artist to sarah brightman and andrea boccelli, and then list them both separate in artist field, sarah brightman/andrea boccelli, and you would accomplishment what ya want."
But then I have to use Artist for everything, and remove Album Artist from all Views that I use, because the album would not appear in the individual artists' listings.
Vincent stated:
"To the best of my knowledge almost all media players, taggers, rippers, etc use ALBUMARTIST=single value and ARTIST=multiple value.
If JRiver would set ALBUMARTIST to multiple, it will become incompatible with almost any other application."
That same objection was made in the discussion of whether to make Artist into a List Datatype, so all that is being requested is to make consistency with Album Artist.
In actuality, in the files, the data is stored as:
Artist = John McLaughlin and Carlos Santana
Artist = John McLaughlin
Artist = Carlos Santana
so I don't see any reason why you could not have:
Album Artist = John McLaughlin and Carlos Santana
Album Artist = John McLaughlin
Album Artist = Carlos Santana
