Tik Tok was released in 2009 as Kesha's debut single and the lead track from her album Animal, quickly becoming a worldwide pop hit and one of the defining party songs of the late 2000s. Its catchy spoken-sung hook and dance-floor beat made it a staple at parties, on radio and in early viral videos, and it later found a second life in short-form edits and throwback trends. The opening remains instantly recognisable, which keeps creators reaching for it for high-energy intros.
