George Strait has just powered through his second Showdown win in a row with his new single, but he's about to face a tough challenge from a celebrated underdog.

The country icon has just released "Cold Beer Conversation," a more mature rumination on what it means to get older that his fans are really grabbing onto. He put down a challenge from Lauren Alaina, pulling out a win with 58 percent of the vote.

Aaron Watson is taking a chance on some more traditional country elements with his new single, "Getaway Truck." Powered by fiddle and banjo, the new track from the Texas native's unlikely No. 1 album, The Underdog, may be just what fans who complain that country isn't country anymore have been looking for. But will they turn out to help him get past Strait?

Listen to clips of both Strait and Watson’s 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.
