Okay I need some serious help, my computer died about 2 years ago with all my songs on it. However, I had them all backed up on my iPod. Today i finally got my dream-Macbook Pro (penryn), and I need to de-authorize all of the other computers that my songs have been authorized on. Because heres the thing, I have no damn idea who has authorization and on what computer. I cant even listen to my own music right now which blows. Is there any way?
