Why do I have so many errors in my log?

Would I be correct in thinking the best way to do this with this particular album would be to the AlbumArtist set to "Emmylou Harris & Rodnet Crowell" and each individual track on the album has artists set as "Emmylou Harris" and "Rodney Crowell" separated by a , or a ;? does that even matter?

I've got a good handful of albums with the same error

Or is there a better way to do it?

Yes, that's exactly it. I'm not sure what tag editor you're using though, so not sure about the proper separator. I think if converting with dbpoweramp you use "; ". If you have a Mac, the Metadatics app lets you add each track artist one at a time.

No clue on your new error.
