Sunday is going to be awesome with Rock Band 2 on my hands, but as predicted, some folks got the game early and unleashing footage on YouTube. Here's "The Middle" and "One Step Closer" for a start (hyperspeed is indeed in) as they are some of my favorite songs.
UPDATE - Modest Mouse's "Float On" Guitar Expert video added.
More notechart footage throughout the week even though u will likely see all the songs on YouTube before the game is officially out (I want this game NOW!!!!)
