this is the most awesomely awesome badass game evah. I actually came to the Sift today with the idea to submit a video like this-because I just checked the game out.
so, cheesemo and others, I can provide some advice, because at first I felt like what you described, too:

in general, the best tracks to enjoy are, quite surprisingly, rock. I tried pretty much everything else apart from classics and hip hop (pop, lounge, trance, etc.) and rock really gets you going the most and seems the most melodic and "in tune"; also, I would STRONGLY suggest everybody to use the double-car setup character, because with it one really finds the synchronous feeling of music and game that you're trying to attain. and yes, it also scores more points
