BIGIDEAS I've used Tuneup for a while and just upgraded. I'm pleased, it meets my expectations and I can't see what the fuss is all about. It cleans up iTunes, adds album art and gives me info about the artists. Now if you consistently rip off music from Usenet it may not work perfectly every time, but it does manage to get it right at least 90% of the time for me. Just a suggestion to anyone using it - remove duplicates and get your library as organized as you can before you start.
