Aside from the bass drum, the perfectly mussed hand-claps and the Phantom of the Opera organ way in the back row, all the extras that give the song its depth and creeping discomfort could have been jacked from Need for Speed if the cars were mounted with lasers (stop lying you post up at ESPN Zone too sometimes). In 'Single Ladies,' Beyonce sounds like a total pro: contained, on-message. Not least because she had one of the best videos of all time.

(Though, admittedly, some would argue that it's neck-and-neck with Miley Cyrus' 'Party in the U.S.A.') Beyonce has given us, finally, a dance craze that requires little more than the deployment of jazz hands with a wrist twist, thus inspiring countless episodes of behind-the-wheel above-the-waist breakdowns and an unfortunate number of full-body dance-floor takeovers. But, since we don't have numbers on this year yet, it's fair to argue that it's the jam of 2009. Sure, Beyonce's 'Single Ladies' actually came out in 2008. In the video for 'Single Ladies,' Beyonce and her back-up dancers spawned parody after parody, featuring everyone from toddlers to grown men to animated chipmunks.
