Sum41, who is most known for their single "Fat Lip", has dropped a few singles into the Guitar Hero universe with the Sum41 Track Pack including "Fat Lip", "In Too Deep", and "Still Waiting" for one purchase of $5.49 (or 550 Wii Points / 440 MS Points). These tracks are also available to purchases of single tracks who would rather pick and choose for $1.99 each (or 200 Wii Points / 160 MS Points). These songs will even be compatible with Guitar Hero: Warriors of Rock as soon as it touches down later this year.
