By the thinnest of margins, Rascal Flatts took care of Uncle Kracker and his new single 'Nobody's Sad on a Saturday Night' yesterday and last night on Taste of Country Nights radio. 'Changed' has now won two in a row and will face another challenger new to mainstream country on Thursday. 

Mumford & Sons are a huge act internationally, but until now, they've stayed off of country radio's radar. 'I Will Wait' is a joyous, bluegrass-inspired jam that showcases this group's full talents. Do they have enough fans to knock off supporters of the better-known superstar trio? Fans will decide today and find out for sure tonight.

Listen to clips of both Rascal Flatts' and Mumford & Sons' 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. 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 again 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.
