Nomcebo, the voice behind Jerusalema, South Africa's global hit

Nomcebo Zikode says the lyrics to the most Shazammed song in history came to her when she was about to lose hope'

It started in December in South Africa, with a few lines of gospel sung in the deep, raspy voice of Nomcebo Zikode and a music video made by fans in Angola - dancers eating their lunch as they moved to South African DJ Master KG's disco-house beat.

Jerusalema, produced late one night at Master KG's studio near Johannesburg, has since become the world's most Shazammed song and a bonafide viral hit - beloved by Christiano Ronaldo, Janet Jackson and a lot of nuns.
