I`ve got plenty of hip hop. Mostly the more intelligent, and less "I`m a gansgter and I`ve sold a lot of drugs" stuff
But for the most part, it is based around the bling and bang in terms of commerciality anyway.
Only the more underground stuff is really more diverse.
Why substitute underground techno for underground hip hop, when what you are talking about is commerciality?
I`m totally unsure about your point?
