My Mac!!!!! :(

I love my iMac. It is 24 inches of beautiful macness! Something is wrong with the optical drive and for some reason it isn't reading music and data CDs. It reads DVDs though, so I'm stumped! I reset PRAM, no good. Off to the Genius Bar at Cherry Hill tomorrow to take her in. Hopefully they have a drive there and will be able to fix it while we browse around the mall! Please keep your fingers crossed!!!
