K-pop fans and hip-hop heads form groups that tend to be mutually exclusive. Mad Decent is trying to change that, teaming up Diplo and the inimitable RiFF RaFF with OG Maco and burgeoning Korean star CL for the new "Doctor Pepper." The record certainly leans to the Zone 6 side, with CL doing a pitch-perfect impression of urban radio's biggest pop stars. Though the neon icon predictably pulls together unlikely pairs like Tony Danza and Colonel Sanders, it's Maco who stars, proving yet again that "U Guessed It" was just one of the many styles he's mastered. Where most cuts like "Doctor Pepper" serve as grand gestures rather than workable records, this should get plenty of play all summer, on both sides of the Pacific.
