The final round of battles on The Voice 2013 kicked off on April 23, and the contestants brought out all the stops! We heard some classic rock tunes, sweet country ballads, and lots of Latin favor. Unfortunately, only seven aspiring singers could advance to the knockout rounds — including one lucky contestant who was "stolen" by another coach after all hope seemed lost!

Read on for the winners of the battle rounds on April 23:
