Congratuations to Florida Georgia Line! The new country duo's song 'Get Your Shine On' won its fifth straight Showdown yesterday and last night on Taste of Country Nights radio. The country-rocker will now be retired, meaning two new singles will face off on Tuesday. It's a battle between a newcomer and a group of legends making a comeback.

Charlie Worsham has released his debut single 'Could It Be,' a soft and peppy love song that showcases the singer's pleasing singing voice. Worsham has earned this shot after years playing in and around Nashville -- perhaps he even opened for Lonestar one day. They're his competition today. The supergroup has reunited, and their new single is the love song 'Maybe Someday.'

Listen to clips of both Worsham and Lonestar'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.

After today, the Showdown will go on hiatus and will return on Jan. 21.

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.
