Britney Spears — “Till the World Ends (the Femme Fatale Remix) feat. Nicki Minaj and Ke$ha”
There’s no question about it — This is the best remix of any song ever. Put the Holy Trinity of pop deities on one track and of course it’s going to be mind-blowingly amazing.
Hands down. No contest. There is literally not a single remix in the world that’s better than this.
