Week after week, contestants on NBC's hit acapella competition 'The Sing Off' tantalize viewers with vocal cover songs, often trying a hand at today's Top 40 hits and easily-recognizable artists. On Nov. 7, the show will mix in a little twang to produce country renditions -- like Carrie Underwood's famous one, 'Before He Cheats.'

Co-ed group Urban Method will be the ones to take on Underwood, and with their performance, they'll stay true to the genre by sporting cowboy boots, big belt buckles and a few plaid shirts. No word on what other country songs will be featured, but each of the six remaining groups will perform one country hit and one rock song to make up the show's 'Classic Rock & Country' night.

Each group is hopeful that their efforts will lead to a big payoff: $200,000 and a Sony Music recording contract. The decision has been in the hands of famous judges Ben Folds, Sara Bareilles and Shawn Stockman of Boyz II Men until now, but online voting will open to the public on Nov. 21. America will decide the big winner during the show's live grand finale, which airs Nov. 28.
