Wow. It turns out that not even a superstar like Keith Urban can stand up to the winning streak Home Free are on with their new single, "Elvira." They are just one challenge away from the Hall of Fame.

The harmony vocal group are joined by the legendary Oak Ridge Boys for the fun and energetic cover of one of the Oaks' biggest hits, and fans have been going crazy, turning out to vote in some of the biggest numbers in Showdown history. They topped Urban with a staggering 75 percent of the total vote -- but they've still got a tough face-off before they can rightfully claim Hall of Fame status.

Toby Keith is one of the biggest, most consistent hit-makers in country music, and his new single, "Beautiful Stranger," will challenge Home Free today and over the weekend. The song is a big, sweeping ballad reminiscent of some of Keith's early hits -- will it be enough to break Home Free's streak, or will they make it five in a row?

Listen to clips of both Home Free and Keith’s songs and vote for your favorite here. You can vote once every hour until this Showdown ends on Monday 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 Monday.

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.
