What happened to black music?

When I got into black music PE was sayin Elvis was a racist and the goverment were suckers. NWA was sayin fuck the police. Now days lil waynes got songs bout fuckin a cop (not in the nwa sense) beyonce goes out with a cop in her new vid, jay z supporting obama and 50 cent said he understands and relates to bush. And everyone else raps bout money sex and sellin drugs in weight.
We got lost along the way.
Well for me its still ftp all the way.
