Justin Bieber vs. One Direction – Pop Clash

Now that long-running Pop Clash champ Pink has taken the win for four consecutive weeks, 'Just Give Me a Reason' has officially retired to the Hall of Fame. Congrats to Pink, her duet partner Nate Ruess and, of course, all of those who voted!

With Pink out of the competition, it's time to match up two completely new contenders for a fan-voted song battle. And this battle happens to be a teenage dream, as heartthrob Justin Bieber is nominated with 'All Around the World' against the adorable lads of One Direction, who are in the running with 'Kiss You.'

Even though 'Believe' came out last summer, Justin Bieber is still pumping out the hits. His latest is in the form of the dance-inducing, super uptempo 'All Around the World,' featuring a rap verse from his 'Baby' collabo partner, Ludacris. The high-energy, club-friendly song was written/produced by the Messengers (Pitbull's 'Feel This Moment,' Chris Brown's 'Don't Judge Me') and finds Justin crooning to a lady: "Baby what you doin', where you at, where you at? / Why you actin' so shy? Holdin' back, holdin' back."

Meanwhile, One Direction are making the girls swoon on 'Kiss You,' the quintet's third single off of 'Take Me Home.' The track is fast-paced, pop-rock love spell with some seriously impressive falsetto from Liam Payne on the pre-chorus. The whole song is bursting with energy, it's almost impossible not to jump around with joy and scream along to the heat-pattering refrain: "If you don't wanna take it slow / And you just wanna take me home / Baby, say yeah, yeah, yeah, yeah, yeah / And let me kiss you."

So, who which song will it be? Justin Bieber's 'All Around the World' or One Direction's 'Kiss You'? Vote for your favorite track every hour below until the poll closes on April 1, 2013, at 3PM ET. Good luck, Beliebers and Directioners!

Rules of Pop Clash: The artist and song with the most votes wins, and the winner goes on to face a different challenger the following week. If an artist wins four weeks in a row, they will be retired into the Pop Clash Hall of Fame in order to give others a chance to compete.
