In what may be every pop music lover's fantasy, Britney Spears has teamed with Ke$ha and Nicki Minaj on a remix of her hit single 'Till the World Ends.'

The remix opens with a fun couple of verses from Minaj, who also happens to be joining Britney on tour this summer. Ke$ha chimes in a bit later with her own take on the song's chorus, auto-tune and all.

But just how does the song compare to the original?
