Since Dev has completely dominated the competition in our 'Sound Off' series for five days in a row now, we are retiring her dance-inducing club single 'In the Dark' to PopCrush's 'Sound Off' Hall of Fame! Congrats to the mama-to-be!

Now, we are bringing you two entirely new contenders -- it's the battle of the boy bands today! We are pitting Nickelodeon's crooning quartet Big Time Rush versus Britain's swoon-worthy quintet One Direction. Big Time Rush has released their newest single 'Music Sounds Better With U' just a few days ago, but One Direction is hot on their heels with the dreamy boy band's newest release 'Gotta Be You.' Listen to both songs here and vote for your favorite below.
