Hip hop and rap can be described simply by: "Show me the wax!" And R&B is not far behind. Hip hop and rap are very workable to college, mixshow, and commercial regular rotation, whereas R&B is more suited to just regular rotation. Again, be prepared with the wax!

Hip Hop and rap have something that no other genre (except maybe metal) has... a strong grassroots album-buying population that does not rely on commercial radio for guidance.

Yes, commercial regular rotation is a huge boost, but hip hop and rap can flourish (and sell a lot of albums) from just college and mixshow spins alone. And this not diminishing: More and more wax is being requested by stations... it is in short supply!
