One Direction
One Direction: After landing third in Britain's 'The X Factor' in 2010, the group quickly emerged as the biggest boy band since the era of Backstreet Boys and 'N Sync. The English-Irish quintet released two chart-topping studio albums, March's 'Up All Night' and last month's 'Take Me Home.' Predictably, tweens swooned, but even cynical critics lauded the group's original, smartly crafted pop.
