Another "official" World Cup song has been named by FIFA and this time it is from the Colombian born singer Shakira. She was recently given the title of official song for the 2010 World Cup. In fact, Shakira will perform the song with South African band Freshlyground at the World Cup. But if you ask anyone else what the official World Cup song is for this year's event they will tell you it is K'naan's "Wavin Flag".
