Can a boy band really fill the shoes of Rihanna, Kanye and Sir Paul McCartney? Welllll, not really. But One Direction's made a very decent go at it when they stopped by BBC Radio 1's Live Lounge and covered "FourFiveSeconds."
And if one awesome cover weren't enough, the group finished up with an emotional performance of "Torn," one of the songs they first performed as a group when they formed on X-Factor in 2010.
