Steven Tyler's debut single is really catching in with Showdown voters, and is competing for the Hall of Fame after winning four contests in a row. The rocker gone country will face a new challenge over the weekend from Craig Campbell.

Tyler's "Love Is Your Name" is the first taste we've had of his upcoming debut country solo album, and it's not quite what we expected from the Aerosmith frontman, with a sprightly acoustic riff and a very poetic, romantic lyric. Campbell's new  single, "Tomorrow Tonight," is sexier than his previous offerings, and seems ready-made to succeed at country radio. Will it be enough to topple Tyler, or will the rocker go on to the Hall of Fame?

Listen to clips of both Tyler and Campbell’s song 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 make 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 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.
