Ok, I have a 27" imac and mostly use it for music. I got on today to put some music on my iphone 4 and to my surprise I have like 12 songs in my itunes library. These songs are a free sampler cd download which I downloaded the other day from Austin City Limits Music Festival. Where did all my music go? Please tell me I haven't lost 35 gigs of music!! I do have an external hard drive that is supposedly used for backing up. Is it possible the music is on there, if so how do I go about getting back into my itunes? Am I missing something here?
