Eminem and other main stream diva's have destoyed hip hop and has given it to a predominantley ignorant audience.. it turns out that 85% of the hip hop consumers aren't of the same race and/or culture of the Pioneers, so yes, there is no hope for so-called Main Stream hip hop, i'll do like Canibus said in his quote..

"Maybe I should leave rap alone/
and just kick my incredible rhymes in the privacy of my own Home"

as long as its on the streets and the traditions are still practiced, Hip Hop will never actually perish, it will have a Cult following years after the Main Streams took away its original supporters..
