It'd be difficult to find a Showdown song battle bigger than this. Two country superstars will square off on Monday and Tuesday after five-day champion RaeLynn gets retired to the Hall of Fame. Her new single 'God Made Girls' topped the Swon Brothers over the weekend, meaning two new challengers will square off this week.

Keith Urban and Luke Bryan have both released new singles from their critically-acclaimed albums. For Urban, it's the uptempo, slightly heartbreaking 'Somewhere in My Car.' Bryan follows up 'Play It Again' with a nostalgic ballad called 'Roller Coaster.' After the high of love brought about by his latest chart-topper, the Georgian dips to a low of a love that did not come and go sweetly.

Listen to clips of both Urban and Bryan’s songs and vote for your favorite here. You can vote once every hour until this Showdown ends on Wednesday 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 Wednesday.

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.
