Canaan Smith stops by CMT Hot 20 Countdown this weekend to help co-host the show. Tune in as we discuss crashing weddings, touring with Brantley Gilbert, his new album, Bronco, and more. Plus, you'll love this week's bonus video -- "Hole in a Bottle," from Smith. Also on the show, we look back at highlights from Blake Shelton, Florida Georgia Line, Little Big Town, Luke Bryan and Sam Hunt -- the 2015 CMT Artists of the Year honorees. And we head to the American Music Awards with Luke Bryan. You won't want to miss it.
