National anthems often celebrate a country's triumph over its former oppressors, like the US national anthem. But in South Africa, the national anthem very consciously combines the music of the African National Congress with the anthem of Afrikaaner apartheid. Call it reconciliation through mashup.
When South Africa ended apartheid and held free elections nearly 20 years ago, it needed a song that would heal the rift created by segregation. Its choice, the country's new national anthem, is part-hymn, part-march, and all mashup. Instead of rejecting the past, it embraced both parts of it.
