I try to stick to Liquid Drum and Bass, especially Nu:Tune, Logistics and Grafix. I try to avoid vocals, as they usually distract me when I'm trying to focus all my attention on the track. Generally it's clean and smooth when I'm in Zone or Time Trial, and Gritty or Heavy when I'm in a Single Race or Eliminator event. But mostly I like my music clean and smooth, I'm just that kind of guy.

For Zone mode, I've been listening to Madmen and Poet's "Scandinavian Sunday" album. It's got a nice chill jazzy groove to it.

I also play some of the tunes from Wipeout Pure or Pulse, I've got both soundtracks.
