It comes on before and after a race. Before the race it sounds like an NES making music. It has a three note bass sequence in order of high,high,mid, then a four note sequence in High mid,low,mid. After the race it has sort of a digitized voice that keeps saying heh as if its laughing or scoffing, with some trumpets playing too.
Sorry if this should be in the music forum, but i feel that the people in the music forum wouldn't know because they may not have DiRT 3.
Also sorry if i have posted gibberish, it is really bothering me because i love the song and i want to go out to get it because its just so darn catchy.
