This isn't a new mashup; it was completed in 2010. Heck, it's not even my first mashup; I recall putting this acapella together with "Esther's" by Amon Tobin. I don't have that first attempt on my hard drive, though. As you can see, this was done before I fully committed myself to bastardizing other people's songs.
