The battle round continues on The Voice this week with a brutal showdown of Bon Jovi. In this exclusive preview, Team Adam contestants Benji and Sam James vie for their coach's favor with an impassioned duet of "You Give Love a Bad Name," ripping into each line with vigor. Benji takes an early command with a throaty delivery of the chorus, but Sam James volleys back with a spirited roar. The judges clearly relish the contestants' aggression, especially Cee Lo Green; he points and nods approvingly as Benji lays into his parts.
