Can Rap Artists Raise Consciousness Through The Spoken Word?

While today's rap artists have been widely criticized for the degenerate lyrics and music videos that project indecency, violence and disrespect for women, some conscious artists are planning to fight fire with fire and create a different,  uplifting social revolution through their lyrics and music. Artist "Rappin Tate Da Great" who is now Brother Tate X has emerged with a new mission: To kill the "N" word and the "B" word forever and change the direction of the popular music so that it restores values of decency, morality, and self respect.  Can it be done? Are radio stations willing to support positive  music or will they continue to insist that more money can be made through the music of degradation? Is this the new spiritual warfare? How can we fight the negative trend in music to win?
