This song shouldn't work. Skrillex's name on the tracklist inspired many eye rolls — it seemed like a blatant, contrived ploy to touch on the already peaking dubstep craze from the subgenre's most prominent face. Until you hear it. A$AP and Skrillex wisely avoided dubstep's expected bass growls in favor of frenetic bending synths, reggae skanks and robot adlibs. It's an adrenaline burst, a much-needed respite from the album's syrupy dream state.
