the first song, "all is fair in love and brostep" debuted as a demo on his bbc radio 1 essential mix. the song "terror squad" by electronic music producer zomboy was inspired by the demo version known officially as "untitled dj tool" or unofficially as "this much power". as a result, skrillex used a sample from "terror squad" that says "it's fucking zomboy", covering up the "zomboy" with a distorted and pitched down laugh.
