Carrie Underwood vs. Jason Aldean – The Showdown

After two months of stability in the winner's circle, champions can't stay seated in recent days. Yesterday and last night on Taste of Country Nights radio, Carrie Underwood's new single surplanted Lee Brice's 'I Drive Your Truck' after just on night on top. Prior to this week, seven consecutive winners have moved on to the Hall of Fame. Can Underwood's 'Two Black Cadillacs' become the next?

To win five in a row, her song will have to top 'The Only Way I Know' by Jason Aldean and friends. The singer performed this hit song at the ACAs last night (Dec. 10), and in fact both artists were on hand to collect awards. It's a true battle of superstars on Tuesday.

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.
