The Dutch DJ Afrojack made his mark on ‘10s EDM by fusing big-room stomp and bold toplines with sly, slippery grooves. His foundation is trance classics like Tiësto's “Traffic,” with its no-nonsense beat and bright stabs, but he also draws from the kind of wriggly groove found in “Beeper,” a fidget-house staple. He's just as rooted in party faves like The Black Eyed Peas' “My Humps”—because a dance floor without a sense of humor is no fun at all.
