"Tik Tok" (styled as "TiK ToK") is the debut single by American recording artist Kesha. The song was produced by Benny Blanco and Dr. Luke and co-written by Blanco, Dr. Luke and Kesha. It was released on August 7, 2009 as the lead single from Kesha's debut studio album, Animal. The opening line of the song came from an experience where Kesha woke up surrounded by beautiful women, to which she imagined Diddy being in a similar scenario. The experience triggered the writing of the song which she later brought to her producer, Dr. Luke, who was then contacted by Diddy in hopes of a collaboration; he came to the studio the same day and recorded his lines and the song was completed.
According to Kesha the song's lyrics are representative of her and based on her life; the song has a carefree message and talks about not letting anything bring you down. The song is a dance-pop and electropop song that uses a minimalist video-game beat interspersed with handclaps and synths. The song's verses use a rap-sing vocal style while the chorus is sung; throughout the song the use of Auto-Tune is prominent. Musically, the song has been compared to Lady Gaga, Uffie and Fergie.
