Tune Up
Got a sloppy, mis-labled, shabby iTunes collection? Put your feet up and let Tune-Up clean things up for you, finding missing artwork and adding missing titles. It's Windows-only at the moment and it isn't free either - for more than 500 songs it's $11.95 a year.
In fact, head over to Doug Apple's Scripts and you can probably cover a lot of these bases yourself, lazy bones.
