Two of the standout performances from the 2015 ACM Awards were George Strait's mini-medley and Dan + Shay's collaboration with Nick Jonas. Fans of one may not have liked the other, so putting the two against each other for today's Showdown made perfect sense.

Strait's "Let It Go" is the new song from an upcoming album. It's a beachy groove that preaches taking things easy. Meanwhile, Dan + Shay are back with more sweetness. "Nothin' Like You" is a love song told like only this duo can. Their harmonies are simply brilliant on the record, and on stage.

Listen to clips of both Strait and Dan + Shay’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.
