Big Time Rush won yesterday's 'Sound Off' with their track 'Music Sounds Better With U,' but the competition was awfully close between the Nickelodeon stars and British quintet One Direction! Big Time Rush came out on top with more than 57% of the fan votes, so today we are pitting the boy band against another pop quartet, Hot Chelle Rae.

Hot Chelle Rae are making waves for their New Boyz featured single 'I Like It Like That,' so we are interested to see if the band, which features 'Glee' star Chord Overstreet's brother Nash, can knock out Big Time Rush and their upbeat tune 'Music Sounds Better With U.' Cast your votes for either Big Time Rush or Hot Chelle Rae below and we'll let you know who wins tomorrow!
