I voted for music. As long as the mix lets you hear the cars. The mix you released was pretty good, could go for a hair more car bias, which I think you said you had in the first edit your computer ate.

I don't care too much what the type of music is, but my 2c, wouldn't use any rap/hip-hop... don't think it goes with drift that well or enjoyed by MOST drifters/fans as much.

I have some footage, including some in-car+tandem stuff. Let me know when you need it by. I'm new in this area and first need to find somebody with a camera to clone the tape or maybe get my boss to buy a firewire card (crap... this is a slimline desktop with no open expansion slots).
