Hm, the same CD that first threw the above behavior is causing me problems in another way -

After ripping, I looked in the folder where I'm saving the files and it had created about 14 different 'artist' folders. It's a compilation album, but I had 'various artists' in the Artist and Album Artist field in dBpa. I had used track-level artists on the tracks themselves for different composers, but why would this override the album level 'various artists' tags?
