At this point, hip-hop has lost its true identity as to who they are and where they come from. I'm sure that most of them don't really forget that, but look at the songs that are out now. Some of the songs are okay to listen to, but if I hear another hip-hop song about material things one more time, I may have to talk to my boss to change the station's format to urban AC and damn the rap altogether. But that's just my two pennies of thought. Depending on what market that you are on, hip-hop may be alive there, but anywhere where you have like a limited number of African-Americans in a population whether the format is urban or urban AC, it's dead to them. Maybe the image of hip-hop has people in the 12+ demo as well as the 18-25 at a stand still. What I'm saying is simply this: It's the sales aspect of the music. It's sinking. The worldly images displayed (nudity, violence, etc.) has pushed way too far as the envelope can push it. You may enjoy it for a while, but later, it will sink and those that soaked in on the image for far too long will have a hefty price to pay in the end.
However if hip hop resurges itself in a better light, it can be listneable again.
That's just my two pennies of thought.
