Celebrate Labor Day Weekend with a little help from CMT Hot 20 Countdown. Cassadee Pope co-hosts this week as we pay tribute to the women of country. We'll chat with the star about her latest video, "I Wish I Could Break Your Heart," and much more. Plus, see who makes our High 5 as we reveal our favorite girl power anthems. Also on the show, we join Carrie Underwood on set, and then we see how country artists react to Taylor Swift's new music venture. Catch all this and more.
