Guys, New MacBook owner, came over from the dark side... Transferring over my iTunes library was simpler than I thought, however, the mess of it is a bit embarrassing. So, is there a tool that anyone can recommend which will scan, clean, add in the album art and not mess up my library further? Note that I've seen Tune Up, but know that it was a port over from Windows. Just looking for alternatives to updating everything manually...!
