In Da Club was released in 2003 by American rapper 50 Cent as the lead single from his debut album Get Rich or Die Tryin'. Produced by Dr. Dre and Mike Elizondo, the track became a worldwide number one hit and a defining 2000s hip hop anthem. Its famous birthday hook helped turn it into a go-to celebration sound long after its chart run. Clips of the intro now circulate in edits, memes and party videos, where the beat alone instantly recalls the original song's confidence and club energy.
