I started off not liking this song, but once I payed attention to the lyrics it just grew and grew on me. "Science is willing when the flesh is weak" is a great line. A very believable and sadly-funny character study of an unscrupulous plastic surgeon. I'm assuming this must be what happened to Michael Jackson. The vocals are pretty sketchy in places, specifically when you're singing at the top of your range, and also around the word "pro". A couple instruments come in that sound really neat, then suddenly appear to morph into your voice... don't really know how you did that, but I like it. Use of the challenge is pretty cursory; seeing as you have a line about reversing the processes, I figured you'd tie the backwards stuff in there somehow.
