Wow, picked up this game this week, and am definitely surprised by all the metal in the game. In the normal game, you have anthrax, lamb of god, spinal freaking tap, etc... But the coolest thing is the bonus songs you can unlock, they have shadows fall, dethklok(yes, the same from the show), and fucking voivod!! X-stream. fun ass song to play on the game. And how proud it was to see the loading screen have a tribute to piggy on there. Guitar hero C.
