Shakira released Waka Waka in 2010 as the official song of the FIFA World Cup in South Africa, and its catchy chorus quickly became known around the world. The song's African-inspired rhythm and call-and-response hook made it a natural fit for football fans, dancers and cover artists. Vocal-only versions later spread online as creators remixed the track, practised the harmonies and built edits around the bare singing. It remains popular because the chorus is instantly recognisable, easy to sing along to and closely linked to celebration, sport and summer energy.
