What artist released the song "Till The World Ends"?

The artist who released “Till the World Ends” is Britney Spears.

The song was released on March 4, 2011, as the second single from Spears’s seventh studio album, Femme Fatale. It is an upbeat dance-pop, electropop, and Eurodance track built around an electronic beat, trance elements, and a chant-like chorus.

The song was written by Kesha, Dr. Luke, Alexander Kronlund, and Max Martin. Kesha said she imagined a touring female singer enjoying a night so intensely that she would want it to continue forever. Although Kesha helped write the song, Spears is the credited lead artist and the performer associated with its original release.

A prominent remix added vocals from Kesha and a rap verse by Nicki Minaj, which sometimes causes confusion about the song’s credited artists. Spears’s solo version reached the top 10 of the Billboard Hot 100, while the remix helped push the single higher on several charts.
