Bad news, everyone! This week's Rock Band DLC offering -- Rush's Moving Pictures album -- didn't come out today as planned. In a post on the forums, Harmonix's Sean Baptiste said, "There is a technical difficulty that is being worked out. I'll alert you when it is all clear." Joystiq wonders if that has anything to do with figuring out how to tell singers they can't wail on "YYZ." It's okay, please stop crying.
