You DON'T want to convert your songs from mp3 to AAC. That's like converting mp3 to mp3. You're going to lose a lot of sound quality. That is a bad idea. iTunes will import mp3, m4a (AAC), aiff, wav, & for windows possibly wmv I'm not sure. See http://www.gnutellaforums.com/showth...threadid=36230 to see how to get the songs into your iTunes Music Library so it can then add them to your iPod.
