Chris Young is a three-time champion on the Taste of Country Showdown, but his new collaboration with Vince Gill is going to need to knock off a new single from his old collaborator to move on to a fourth straight win.

"Sober Saturday Night" made easy work of Old Dominion's latest single over the weekend. The love-lost ballad will now square off against Cassadee Pope's "Summer," her brand new single and the title track to her just released EP. It's a flirty summer love song that features an extremely sexy music video. Of course Pope and Young sang together on "Think of You," and during the subsequent tour became very good friends.

Listen to clips of both Young and Pope’s songs and vote for your favorite here. You can vote once every hour until this Showdown ends on Wednesday at 8AM ET, so come back and vote often to be sure your artist wins. The winner of this matchup will face a new challenger on Wednesday.

Showdown Rules: The song with the most votes wins, and the winner goes on to face a new challenger in the next Showdown. Vote as much as once per hour online. If a song wins five Showdowns in a row, it will be retired into the Taste of Country Showdown Hall of Fame to allow for new songs to compete. Some songs will be considered for a second Showdown if voter turnout is healthy in a losing effort.
