Madonna feat. Justin Timberlake – 4 Minutes  

BEST MOVES

She's the queen of reinvention, and didn't become a millionaire (x 325) for nothing. Over the course of her 25 years in the spotlight, she's delighted in rankling the general public with her music, her videos and, of course, her coffee table book. You could probably argue that Mads is the greatest pop culture icon of our generation, flitting between personas, tackling taboos and basically playing the media like a maestro.  Throw Justin Timberlake into the mix, and you have a chart match made in heaven.
