'"Test 01'"

SO, my last.fm page has a track on it, that I have no recollection of making:

http://www.last.fm/music/Critical+Best/_/Test+01

It's called 'Test 01', and it's over 40 minutes long. Evidently, 7 people have listened to it, some of them multiple times.

Does anyone have it? Seriously, it's not on any of my hard drives, and I really don't remember making a 40 minute track...
