Well, my Rockband disc cracked. But not a normal crack. It went from the base, mid way and round, like an oval. Yet, it still worked two or three times with the crack, now it's died. It's a bit gutting since I was going to buy RB2 and upload the songs to it. Blu-ray discs are suppose to be durable but this one broke and it's the disc I take the most care of.
