We talking about the state of rap musics effect on black culture,.. What would Lennon and Sam Cooke who both technically died before rap music have to do with this??
Because the effect that you are talking about is violence. Violence has been around since humans have existed. Our community's homicide rate was higher BEFORE Hip Hop. It was high back when Hip Hop music that wasn't violent was popular.
The homicide rates in our community are high now for reasons that have no correlation to Hip Hop music.
Why did I bring up the other artists? Because they are musicians. Is Hip Hop not a form of music? Are rappers not musicians?
