I was originally linked to this on another forum where the average user's appreciation of electronic music is eclipsed only by their love of getting high and listening to electronic music. Synaesthete should be simple to figure out for anyone who understands DDR, Guitar Hero, Rock Band, or any other game involving hitting a button when a scrolling bar, circle, or whatever hits the right point on the screen. Since TFP has a fair number of electronic music enthusiasts and a whole bunch of gamers, I figured I'd post it here.

Get high (if you're so inclined,) crank up the bass, and play.
