by Claudine Zap The vuvuzela is the South African horn that â€" like it nor not â€" has provided the buzzing background to the World Cup . And now it has its very own pop song. In response to a proposed ban on the blare, a team of producers pulled together a dance track called "Blow That Vuvuzela." Now the annoying stadium ambiance has become an annoyingly catchy song . Not that the fans need any encouragement to "blow that vuvuzela." But there is something to the song.
