Also on the show, we started out with 64 music videos, and now the fans have spoken. Find out which one is named the winner of our Hot 20 Bracket. Plus, we talk to Little Big Town about their controversial single, "Girl Crush," and get the scoop on Blake Shelton and Luke Bryan's ACM Awards hosting preparations.
