A team of songwriters and producers worked on this track, with eight getting songwriting credits and more added later. Let's try to sort them out:
Producers: Dr. Luke and his frequent collaborator Cirkut, and also the English producer Sermstyle. They also received songwriting credits.
Writers: Kesha, her mom Pebe (who has written several songs with her daughter), Pitbull, Priscilla Renea, Breyan Isaac.
Around this time, many hit songs were written by committee, but not all: Pharrell Williams wrote "Happy
" on his own.
