22 is a track from Taylor Swift's album Red, released in 2012 and issued as a single the following year, written as a celebration of being young and carefree at that age. Its chorus became a shorthand for birthday culture, especially for people turning 22, and it has stayed in regular rotation at parties, on radio and in social video edits ever since. The song's longevity comes from that simple association: whenever a creator wants an instantly recognisable marker for youth, friendship and a milestone birthday, this hook still does the job.
