Yeah, I've definitely been having problems with tag info showing up correctly. I spent a while today using easytag to add album art to several albums and then retransferring them to my s9 only to find that, not only did the album art not show up, but it also caused the rest of the tag info to go bye bye (unknown artist, etc.) The tag info is definitely still there on my computer though. Guess I need to make sure they're all jpgs.
Maybe it's my program... Does anybody know if mp3tag works well under wine?
