A few years I heard a radio interview with a prominent rap artist (I forgot who) who said something like: There's some evidence around that the government does consider rap and hip-hop to be, in a variety of cases, a potential threat on the order of political speech.

The supposed reason is that if you had to pick one artform with the highest potential to start widespread political action in a short time, it would probably be music. And one of the demographics that presents a significant potential political threat to established order (ie large-scale city riots) it is the audience for rap and hip hop.
