Sorry if this has already been covered, but... My iTunes music library, which is MP3-encoded (not AAC) is missing 43 tunes I downloaded from Limewire. Perhaps the tunes weren't MP3s, though I'm usually careful to check they are. Is there an easy way to check all my iTunes libary is MP3s, or is there some other solution to restore the missing 43 tunes? Any help appreciated.
