"Waka Waka" was written by Shakira and John Hill and co-produced by John Hill.[2] The track, which samples the chorus of the 1986 Cameroonian hit song "Zangaléwa", by Cameroonian band Golden Sounds,[4] features Afro-Colombian instrumentation, Soca beat and South African guitars.[5][6] The song consists of rhythmical African sounds, and represents the vitality and energy of the host continent.[7] Indian music composer duo, Salim-Sulaiman, collaborated with South African singer Loyiso Bala and Kenyan singer Eric Wainaina to record the anthem for FIFA World Cup 2010.[8]
