There are a few songs that are constantly played at the World Cup. There is the K'Naan theme song called "Waving Flag" and then there is the Shakira song which I think is called, "Check Out How Fast I Can Shake My Butt." However, there is another song that I'm not sure people are hearing on TV. It's a song that is constantly played at the stadiums called "Shosholoza." "Shosholoza" is a traditional South African folk song about a train that keeps going forward.
Here's the lyrics according to Wikipedia:
Shosholozah
Shosholozah
Ku lezontabah
Stimela siphum' eSouth Africa
Shosholozah
Shosholozah
Ku lezontabah
Stimela siphum' eSouth Africa
Wen' uyabalekah
Wen' uyabalekah
Ku lezontabah
Stimela siphum' eSouth Africa
A rough translation:
Go forward
On those mountains
Train from South Africa.
Go forward
Go forward
You are running away
You are running away
On those mountains
Train from South Arica.
