Why does the mainstream media advocate l!ber@lism and songs about sex and partying?

People have been singing about sex and partying for as long as music has been around. The song "Greensleeves" written in the 1580s is about a prostitute, and Mozart wrote a song called "Lick me in the ****." Even in the 50s and 40s, people were singing about sex. Many early blues, jazz, and rock songs had sexual overtones. Listen to "Tutti Frutti" or "Rock Around the Clock" again and tell me you don't hear sexual stuff. BTW Slipknot blows.
