I downloaded this tune and uploaded it to my first gen Xbox about ten years ago. I just soft-modded my Xbox and ripped all the music to my PC HDD. Being lazy as hell back then I didn't bother naming any of the tracks. I've identified them all apart from this one. I've tried to identify the song loads of different ways but with no luck. I vaguely remember to being credited to Aphex Twin, however, I'm pretty certain it's not him. If anyone could shed some light it would be appreciated as it's a pretty slick number.
