Rumor: Dueling Rock Band 2 Tracklists

There are differing leaks out there regarding the track list for Rock Band 2. Both are unattributed, one to a friend of a friend who got a look at an email from Harmonix to MTV or something. But in the interest of rumormongering, we'll repeat both with the caveat that there is no way of knowing if this stuff is for real or not. But if, combined, they're half right then this could be one hell of a track list, possibly the best of any rhythm game.
