Flo Rida has become the latest artist to snag the 'Sound Off' crown, beating out Mike Posner in yesterday's battle with his Sia-featured track 'Wild Ones.' Today, we'll see if the club-ready rapper can take out sexy superstar songstress Katy Perry and her revamped version of 'The One That Got Away,' which features some verses from Atlanta rapper B.o.B.

On 'Wild Ones,' Flo and Sia deliver infectious hooks over an uptempo, feel-good, effervescent dance-pop beat. On the other hand, Ms. Perry's catchy remixed version of 'The One That Got Away' is more of a midtempo tune, with hard-hitting drums, melancholy pianos, chiming sounds and violin-laden verses from B.o.B.

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!
