Home Free have taken yet another round of the Showdown by a stunning margin. The harmony vocal group took more than 90 percent of the vote in their latest face-off, but now they'll face a challenge from a country superstar.

The group's latest single is a cover of the Oak Ridge Boys classic "Elvira," featuring the Oaks on the track. Fans have been turning out to vote like crazy for the song, which is definitely a fresh, fun and energetic take on the tune.

Keith Urban has just released "Break on Me," which is a ballad that puts him  in a new light. The song assures a loved one that they can lean on him whenever they need to fall to pieces, and it's a powerful message that his fans are likely to embrace. But even Urban may have a hard time overcoming the fanatical voting block for Home Free and the Oaks.

Listen to clips of both Home Free and Urban’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.
