Gamers who pre-ordered Guitar Hero World Tour were given a little sheet of paper instructing them to go to a website in order to receive a cheat code that would allow us to unlock all 84 songs included with the game at once. While I play Guitar Hero solo more often than not and prefer unlocking the songs manually, which gives the whole experience a game sort of vibe, I know some of you are impatient and don't want to be stuck playing the songs you don't like when you could be playing the songs you do, so I've gone ahead and placed Kotaku's screen grab of the code and inserted it below; have fun!
