Carrie Underwood's new single is turning out to be an unstoppable force in the Showdown. 'Something in the Water' just won its third straight contest, topping Brett Eldredge in a landslide. Will the country superstar roll on to another victory?

Not if Dierks Bentley has anything to say about it. Bentley's new single, 'Say You Do,' is a heartbreak ballad that's as good as anything he's released in his career -- maybe better. The fourth single from 'Riser' may just be the song to give Underwood a serious run for her money.

Listen to clips of both Underwood and Bentley’s songs and vote for your favorite here. You can vote once every hour until this Showdown ends on Friday 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 Friday

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.
