It’s called MPFreaker and it’s amazing. Waht it does is scan your library and automatically put in whatever you’re missing. This includes ordinary things like title, artist, and album bu it also includes album art and lyrics! If you’re a nut like I am about your iTunes library you need this program. One other uber geeky thing on their website is a mac OS X version of Ultima III. Yes, that game… It is so much better on a newer machine, no more overheating 1541 disk drives!
