I'm dissapointed over the lack of any Twisted Sister songs. There's a character in the game who looks a lot like Dee Snider, I would have thought Brutal Legend would have some of their songs. Not gonna take it, I wanna rock, those would have fit perfectly with the feel of the game. And there's no AC/DC either. And Whitsnake, seriously, for my people Whitesnake is a running gag.
Maybe a bit of Iron Maiden wouldn't have hurt either.
