Newcomer Olivia Lane's fans had a busy weekend. The "You Part 2" singer's faithful woke up early and stayed up late to make sure her song knocked the new song from Cam out of the ToC Showdown. Her next battle against an established hitmaker may prove to be more difficult.

Hunter Hayes' new song "21" is the first from an upcoming third studio album. The easy-to-sing pop-country tune is a party song at its core, but not in the style of the genre's wildest revelers. It's more innocent, like so many of this 23-year-old's best songs. Hayes' fans would be wise not to take this matchup for granted, as Lane's supporters have proven they'll fight.

Listen to clips of both Lane and Hayes’ songs and vote for your favorite here. You can vote once every hour until this Showdown ends on Wednesday 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.

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.
