I have it!
See, I was bored once so I took a bunch of my audio files, converted them to .WAV, then reversed them.
All of them sucked, except for "Boulevard of Broken Dreams" and "Simple and Clean".
Anyway, it's actually pretty cool, the melody's alright. I have it on my Ipod and I listen to it every once and a while.
I suppose I could put it on filefront for ya.
