It's on a CD, it's mp3 files, which means most likely it wasn't a cd made for me by someone, and also, the label -- which just says "WES/FAITH" appears to be in my own handwriting.
It's very obviously not my soundrack, as I only know about half the songs; someone either made the cd for me and I labeled it, or someone posted their own soundtrack for download, and I downloaded it and burnt it to data cd for some reason, then put it on a shelf, and completely forgot about its existence. Hrrm.
ETA: Ahh. T'was made by zortwife, and shared by zortified.
