2010's FIFA World Cup in South Africa gave us R. Kelly's "Sign of a Victory" (an official anthem) and Shakira's "Waka Waka (This Time for Africa)" (an official song). This year, with the World Cup taking place in Brazil, we've got Pitbull (Dalé!), J.Lo (Luh Ya, J.Lo), and Brazilian artist Claudia Leitte with their contribution for official song: "We Are One (Olé Ola)." In case you were wondering what to do with yourself during the sports, the sing-along chant is "Olé, olé, ola." Easy enough.
