Two country superstars square off in today's song battle. The Taste of Country Showdown has rarely featured two more well-known artists. Reba McEntire, fresh off a big victory over Luke Bryan, will take on Tim McGraw's first single from a new album.

"Until They Don't Love You" is Reba's sassy yet heartbreaking single from her Love Somebody album. It's one of the more musical songs you'll hear, and fans seem to be loving it. She topped Bryan's "Strip It Down" with 63 percent of the vote over the weekend.

McGraw may not be as easy. The new song from an upcoming album is similar to many lead singles the "Shotgun Rider" star has previously cut. If there's anyone with a more rabid fanbase than Reba, it's him, but ToC readers will ultimately decide.

Listen to clips of both McEntire and McGraw’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.
