#24. Britney Spears f/ Nicki Minaj & Ke$ha "Till The World Ends (Femme Fatale Remix)"

Producer: Dr. Luke, Max Martin, Billboard

Label: Jive Records

Complex says: It was clear when Britney teamed up with Ke$ha and dropped “Till The World Ends” that she was back to claim slutwave supremacy. However, when Nicki Minaj joined the party for the remix, she took the song to an entirely different level and ethered Lil Kim yet again. The dance club monster of a record gave the original the boost it needed to remain at No. 1 on the Billboard charts. More than a decade deep into her stellar career, it’s yet another radio smash for Britney.
