I understand what Mark is trying to say. If you are trying to mix music into the video, make the music a part of the video, not some distant ambient noise. This video could have been done with no music, to be honest.
Anyway, it was fun to watch. Japanese street drifting is incredible. These guys have some balls, and I'm not only talking about the drivers. The spectators just chill on the sidewalk while cars are coming by sideways 2 or 3 feet away. The driving is inch perfect. If it was me, I'd hit the curb and flip my car first run out. lol.
