hip-hop music

Actually I did not have good image about hip-hop music, I was thinking most of hip-hop music is just noisy and only about money and violence. But after Billy Drease Williams lecture, I noticed hip-hop music also has artistic aspect and I was really touched by that lecture. Probably many people have dirty image about hip-hop music like me, but I think this kind of stereotype is should be removed. We have to understand hip-hop music is developing and has artistic aspect like Drease's music.
