Joe Nichols and his fans didn't just pull off an upset by taking down Tim McGraw and his new song last weekend, they thumped him. 'Yeah' grabbed almost 70 percent of the vote, more than enough to move the new single along to a second round of the Showdown, against another country music superstar. 

Rascal Flatts are back with new music in 2014. 'Rewind' is the first song from the trio's upcoming, still untitled new album. It's a creative new love song that steers in a slightly new direction without alienating fans who've grown to love them over the last 15 years.

Listen to clips of both Nichols’ and Rascal Flatts’ 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.
