In the No. 5 video on our Top 10 Music Videos for the 2012 Apocalypse, Madonna and Justin Timberlake are facing obliteration in their '4 Minutes' clip. Madge and JT are dancing away their remaining four minutes on earth, as a weird, three-dimensional substance eats away at every last creature and material good left on the planet. The queen of pop and her boy-toy JT manage to escape up until the end of the video, when both of the entertainers are cornered with nowhere to go.
