Rap spreads revolution, or revolution gets expressed through music?

Why has rap — an American music that in its early global spread was associated with thuggery and violence — come to be so highly influential in these regions? After all, rappers are not the only musicians involved in politics. Late last week, protests erupted when Youssou N’Dour, a Senegalese singer of mbalax, a fusion of traditional music with Latin, pop and jazz, was barred by a constitutional court from pursuing a run for president. But mbalax singers are typically seen as older entertainers who often support the government in power. In contrast, rappers, according to the Senegalese rapper Keyti, “are closer to the streets and can bring into their music the general feeling of frustration among people.”
