adding Rap stations to my Pandora Toolbar?

i already know about the Add/Edit stations for pandora toolbar, i try it and i can't get anything. i try the Local Stations and i get something.

i'm trying to find good rap stations i can add my pandora toolbar, ones that actually work. instead of having to listen to Local Stations.

can anyone please help me.

Rap Stations that include Ludacris, Plies, and all the other famous rappers.
