In yesterday's 'Sound Off' battle, Dev's Eurodance-inspired dance track 'In the Dark' duked it out with Rihanna's new club banger 'We Found Love.' Dev prevailed, raking in more than 80% of the votes casted! Congrats to the fly mommy-to-be!

Since Dev was the champ in yesterday's 'Sound Off,' today we are pitting her against the speedo-wearing, party rockin' duo LMFAO and their wiggle-inducing jam 'Sexy and I Know It.' Will 'In the Dark' come out on top once again, or will 'Sexy and I Know It' dominate this time around? Cast your vote for either Dev or LMFAO 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!
