Blazing out of high school obscurity to the top of the charts, The Arctic Monkeys built a huge internet following before releasing their first full-length album in 2006. "Whatever People Say I Am, That's What I Am Not" was a huge hit, topping the charts in the U.K. It won the Mercury Music Prize and had hits with "I Bet You Look Good on the Dancefloor" and "When the Sun Goes Down."
