Gamers and musicians are more and more the same person in 2012, making the playing of video game music more common. Take Bit Brigade, for instance. I've never heard of them, but they rock the Casbah. In this video they rock Mega Man's Casbah. They play the musical score to Mega Man while their in-house gamer savant performs a speed run through the game. The video is 44 minutes, so brace yourselves for mega music excitement.
