After a mini-holiday, the Showdown returns today and tonight on Taste of Country Nights radio, with reigning champion Thompson Square well-rested to take a high-powered challenger. Kelly Clarkson and Vince Gill's duet of 'Don't Rush' is up against 'If I Didn't Have You,' the latest from the husband-wife duo. 

Clarkson and Gill debuted their song at the CMA Awards on Nov. 1, and since then, it's become one of the most downloaded songs in country music. Thompson Square's new single is a two-night champion. The first song from their upcoming new album is an easy to embrace love song that their fans have really gotten behind.

Listen to clips of both Thompson Square's and Clarkson's songs and vote for your favorite here. You can vote once every hour online, so come back and vote often to be sure your artist wins. Hear the full versions of the songs tonight after 10PM on Taste of Country Nights. Help your favorite song win by placing additional votes at (888) 678-9995. Call as many times as you like! You can listen to the show online through any of the 41 radio stations that carry it. Voting will end tonight at 10:40PM CT.

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, and as much as you want by calling (888) 678-9995. If a song wins five days 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.
