5. Wavin' Flag by K'naan (South Africa 2010)

K'naan's celebratory song inspired by the stories of refugees was used in Coca-Cola's 2010 World Cup campaign. Although this song wasn't part of the official FIFA compilation, "Wavin' Flag" turned into an alternative anthem. Many fans considered this song to be catchier and have a more positive message than Shakira's "Waka Waka."
