Purple Motion is too slow, what you need is somehting like Radix or Beek. Heck, even Elwood, but I think most ppl used his songs already, then again Hyperlite is also good, but I used all his songs

Apart from that, a whole Different lien of cool is DJ Bourg, his one song called Goa Jungle is the best mod I've ever heard, btu at 2mb its too big for JJ2. The list is endless, I like hunting for my own mods though
