DONT!!!
Do not sign up for Zune, do not do anything with Zune. They are bad and dumb. They've been charging me for 3 months, when I was never subscribed to them, and they have no fucking costumer support!!! I've been in a chat with a microsoft employee for the past two days and he's doing his best to help me, but there is nothing he can do. You cannot unsubscribe from Zune yourself, you'll have to get help to do it. I am going to seriously... I don't even know... just don't support Zune!
I ust to have a Zune, Returned it after the next 2 days I had it.
