The main theme music from Rad Racer (NES, 1987) is really under-appreciated, I think. Although that may be because it was one of my favorite games as a kid. I'm pretty sure the composer was Nobuo Uematsu. I think a rock or metal remix would be awesome, maybe with some electronic or techno elements.

The other themes aren't bad either, though they aren't really that interesting on their own. Maybe parts of them could be combined with the previous theme.

And here's a video of some of the gameplay. (this game was devilishly hard, I rarely made it past the third course, since running into anything more than once was like game over)

(by the way, this was the music on the Strong Bad episode where he becomes an anime character, if any of you have seen it).
