If you ever played Civilization 4 you'll know Baba Yetu, the theme song for the game.
It's the work of composer Christopher Tin, who ended up winning a Grammy for the song and in the process, Civilization 4 became the first video game to win a Grammy.
Now, it's another first for Baba Yetu, which has starred in America's Got Talent.
