One of the summer's hottest new songs will be next to take on superstar duo Miranda Lambert and Carrie Underwood. 'Somethin' Bad' squeaked past 'Drunk on a Plane' by Dierks Bentley over the weekend, setting up a matchup with Brothers Osborne.

The brothers have released 'Rum' as the second single from their upcoming album. The easy to appreciate summer groover will make you feel like you're on the beach, even if you're stuck in a cubicle all day long. Can a duo of newcomers find the fans to top a duo of superstars?

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.
