You know what really carried the whole "hip hop" movement? The parts you don't see, the parts that were and are hard to corrupt. The dancing, and the graffiti. The graffiti for obvious reasons, defacing public property, drawing over other people's shit. It pops out at you, it's supposed to fuck with you, that's the whole point of street art. There's a lot of pride and technique in making a nice piece, but you can't be attached to it, because someone is going to paint over it, or your name starts getting known, which brings unwanted attention. The dancing to a lesser extent, because the people that take that shit seriously, don't do it for money but for personal pride. That's why they're so cocky and arrogant, they put in a lot of work to do what they do. The rap shit, is too commercial and you need beats(DJ's) to have rap, so the two kind of fall into the same corruptible fold, anything that has to be mass produced has to be watered down, unfortunately. It's either cost or just physical logistics. You have to rely on economies of scale to survive in that industry and there's a lot of competition, so it's easier to just sell your soul.
