In Da Club was released in 2003 as the lead single from 50 Cent's debut album Get Rich or Die Tryin', with production by Dr. Dre and Mike Elizondo. Its pounding beat and birthday-themed hook made it an immediate club and radio staple, and it quickly became shorthand for a night out in films, sports arenas and celebrations. Two decades later the track still circulates through short-form video, where creators reuse its most recognisable moments to signal confidence, arrival and a party atmosphere without needing any explanation.
