Re: The unofficial Rock Band thread.
Apparently 2 packs:
Rock Band is excited to offer a new Billy Joel edition of the popular video game, providing a masterful keyboard experience of his music to fans around the world through two downloadable game packs: a "Hits" pack of 12 songs arriving in December 2010 followed by a 6-song "Piano Challenge" pack in the spring.
Fred: War, Nobby. Huh! What is it good for?
Nobby: Dunno, Sarge. Freeing slaves, maybe?
Fred: Absol—well, okay.
