Today's Sound Off finds a fresh batch of competitors duking it out for the most fan votes. Last week, Kelly Clarkson was named the ruling queen of Christmas after winning the Sound Off five times in a row for her track 'I'll Be Home for Christmas,' putting her in the Hall of Fame. Now, Sound Off newbies Flo Rida and Mike Posner will take on one another in a battle of the songs.

In his new song 'Wild Ones,' Flo gets an assist from Australian songstress Sia to create a club-ready, dance-pop tune. On the other hand, Posner blends a hip-hop back beat with some high-pitched synths for an infectious tune on 'Looks Like Sex.' Which song do you prefer? Cast your vote below!

Rules of ‘Sound Off’:
There’s only one rule for our ‘Sound Off’ series: If a song remains the reigning champ for five straight days, it is retired to PopCrush’s ‘Sound Off’ Hall of Fame. With tons of great tracks coming out everyday day, we have to give other artists a chance to win!
