I just discovered last night that if you imported a CD with iTunes and for some reason did not have the CDDB look up the information you can actually look them up later. Just select the tracks you want to try and choose get CD Track Info. That saved me so much time last night as I didn't have to update about 200 tracks that were imported while I was using dialup and didn't feel like dialing in for a CD lookup. Too bad it only works on tracks that were encoded using iTunes.
