MP3 files included in library with
- Title
- Artist
When I click on properties of a file, it completes the album artist field and when I click okay it saves the album artist. This is correct behaviour.
HOWEVER, if I don't do that and do a search for album artist, or if I use an auto-organize rule that includes Album Artist, album artist is now 'unknown'. It formerly defaulted to the track artist.
It doesn't seem to properly default the album artist if it wasn't completed anymore.
This just broke all my previously-correct auto-organize rules that include album-artist and formerly defaulted correctly.
