We travel to Austin, Texas, for the iHeart Radio Festival on this weekend's CMT Hot 20 Countdown. Tune in as we hang out with your favorite artists, including Keith Urban, Miranda Lambert, Zac Brown Band, Sam Hunt, Florida Georgia Line and more. We'll get the scoop on Miranda's summer plans, a cool collaboration Keith has in the works, and Florida Georgia Line reveal their bad habits. Also on the show, we have the exclusive world premiere of Parmalee's brand new video, and see which video nabs the top spot. Enjoy the show Saturday and Sunday mornings at 9/8c.
