[Slade]

This song, by a group called DAI, is unlocked when you beat Viewtiful Joe on normal. I've known about it for a while, but I just got the mp3 today, and suddenly realized how cool it was. If you were to classify this song, it would accurately be called "Japanese video-game nu metal." I know it's the most bizarre combination ever, but give the song a chance; it's nuts, but in a good way!
