There have been 3 songs featured in the trailers. I've read that the most prominent song is by 30 Seconds to Mars. The other two are covers. One is "Ghost Rider" and the other is "Tainted Love." I have no idea who does those tunes though.
Can you be more specific? --- http://jalopnik.com/5564174/hyundai-spoofs-top-gear-with-top-deer
