It doesn’t happen a lot, but when it does, it is SUCH a royal pain. You stick a CD into your computer to import mp3s into iTunes, and iTunes doesn’t know the names of the songs on your CD. So you’ve got to type them all. ugh.
Well, I can’t solve your problem, but you can prevent someone else from experiencing the same frustration. iTunes actually uses a service called Gracenote (also known as CDDB), which is essentially just a massive archive of every CD ever made (Well, every CD except the one you just tried to import.) And you can submit the information about the CD to Gracenote on your own, and then everyone else who pops that CD into iTunes (or Winamp, or QMP, etc.) will be reading the information that YOU entered.
