John King just needs some Labor Day love from his fans to put his debut single 'Tonight Tonight' into the ToC Showdown Hall of Fame. One more win and the country newcomer's hit will join some of the greatest songs of the past two years. He took care of Darius Rucker's latest earlier this week.

This weekend, he'll need help to beat the Cadillac Three, a country trio with a sound as amped up as Nashville will allow. Jaren Johnston and company were voted most likely to get a noise violation ticket in high school -- OK, we made that up, but when you hear 'Party Like You,' you'll understand why that's conceivable.

Listen to clips of both King and TC3’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 Wednesday.

Listen to John King, ‘Tonight, Tonight’

Listen to the Cadillac Three, ‘Party Like You’

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.
