Miranda Lambert's new song 'Somethin' Bad' cruised through two rounds of the Taste of Country Showdown, but she may be facing her toughest challenge yet in a song that's been all over Twitter and Facebook this week.

Jana Kramer has released 'Love,' the first single from her upcoming album. The bittersweet tune feels as personal as anything you'll hear on the radio. Despite everything she's been through, Kramer still believes in love. The catchy single will need support from all of its fans to top a collaboration between country superstars.

Listen to clips of both Lambert and Underwood’s and Kramer’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.
