Essays like this really make me shake my head. "Should we eradicate hip hop?". As if they had some choice in the matter. Questions like that show they don't really understand the issues.
I'm old enough to remember that record labels HATED hip hop. They had complete contempt for it as music and as a commercial product. Hip hop literally could not be stopped and those old guys who ignored it are all gone now.
So banning it, whether it be from television or the radio, won't stop it. A little thing called the internet is becoming the dominant form of consumption of hip hop anyway. And we know that can't be policed.
Here's another had to accept fact: you can't MAKE a hit. You really can't. If you could, the entertainment business would be a lot more profitable than it is. But most books, movies, TV shows and albums FAIL because they CAN'T convince people to consume it, no matter how much they spend making it or selling it. I don't want to give specific names, but we support those "balance" artists when they come along and they sell...some times a little, some times a lot. It depends on how appealing their music is.
At the end of the day, you can't legislate art. People will buy the "wrong" artist, and people will ignore the "right" artist. This is not a BET issue, this is a life issue.
