With one more win, Song Suffragettes singer Kalie Shorr's new single will be enshrined in the Taste of Country Showdown Hall of Fame. "Fight Like a Girl" made easy work of Brandy Clark's latest over weekend, setting up a battle with a hot country duo.

Brothers Osborne's new single from the Pawn Shop album is called "21 Summer," and it's singer TJ Osborne at his very best. The emotional lost-love song reflects on a perfect summer romance that casts a shadow over all others that have come since. The duo will need a big effort from fans to top Shorr's faithful, however. The newcomer is a force to be reckoned with.

Listen to clips of both Shorr and Brothers Osborne’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.
