Kane Brown is right on the verge of winning his way into the Hall of Fame with his debut single — but first he'll have to get past a very difficult dual challenge.

Brown has been on one of the biggest winning streaks in Showdown history with "Used to Love You Sober," his official debut single. Although the young aspiring star doesn't even have a record deal yet, his very dedicated voting block has shown up over and over to give him victories over established stars like Luke Bryan and Carrie Underwood.

LeAnn Rimes has just released "Celebrate Me Home," the single from her new Christmas album, Today Is Christmas. She invited Gavin DeGraw to join her for the cover of the Kenny Loggins classic, which she and DeGraw have re-slanted to pay tribute to our military. Will the combined voting block of Rimes and DeGraw be enough to prevail, or is Kane Brown headed for the Hall of Fame? Only your votes can decide.

Listen to clips of both Brown and Rimes' songs and vote for your favorite here. You can vote once every hour until this Showdown ends 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.
