The fellows over at Destructoid have done a little detective work, collecting several new tid-bits from various sources. Most prominent is the addition of R.E.M.'s "Orange Crush," the classic Agent Orange-inspired single from 1989.

Also added to the lineup as an unlockable song is Flyleaf's "I'm So Sick," as well songs from bands Anarchy Club, Bang Camaro, Freezepop, the Acrobrats, and Vagiant.
