Well, I thought that this board could use a little competition. So this thread is for setting up any challenges you want people to attempt to do in Audiosurf. State the song name, any conditions you have, and a link to where the exact same song you used can be found.

So to start:
Track: REMIYAX V4
Conditions: Achieve Gold with any Elite character
Link: http://www.megaupload.com/?d=C569A0IO
(Note: File also contains all the individual tracks that make up this track, as well as the previous three REMIYAXes)
Just a note of warning before attempting - this track is 55 minutes long. The Gold medal requires a score of over 1 million. Don't attempt to use the map to tell what's coming next - it's so compacted you can only gauge general trends.
