“Waka Waka (Esto es África)” was the official song of the 2010 FIFA World Cup in South Africa, recorded by Shakira in English and Spanish. It's a pep talk: you've trained, the pressure is on, keep your eyes on the goal, get up when you fall — this is your moment.
Its chorus borrows from a Cameroonian soldiers' song, “Zangalewa”, and the music is built on African rhythms and guitar. The Spanish version is one of the best-known Spanish songs on the planet, and its lines are short and repeated, perfect for a first sing-along.
Listen for the commands: Spanish uses the imperative a lot in sport and in songs like this — get up, go, keep going, feel it. It's a quick way to learn how Spanish tells someone what to do.
