"Everything has a drop," Skrillex says. "When you listen to funk, and it starts out with the drums, and then the bass line comes in, that's just a kind of dynamic. When something cuts out and the anticipation of something else builds, and the surprise of what it could be. I think all dance music has that in that sense. Even something like techno, even if it's just a kick drum, it's still part of the dynamic."
