I am by no means an expert, so I’d be so happy for your thoughts about my limited understanding. It seems to me that there is (1) hip-hop culture and (2) its creation, rap music. Rap does not inherently depend on hip-hop any more, as rapping can be [and often is] about anything. Hip-hop seems to still depend very heavily on rap as a means of expression (via lyrics).
Regarding sales, rap seems to be doing superbly, and it has influenced nearly every form of popular music that I can think of.
The hip-hop part is where things get interesting. I recall Vanilla Ice’s career being terminated when it turned out when he dishonestly said that he was from “the streets” (that talk about 9mm pistols and 12 gauge shotguns ). There were other studio gangsters for a while, but after that, there were real gangsters, where some had been shot multiple times. Some of the beefs became fatal (Tupac, Biggie, etc.). Some of the business people in the industry seemed to be legitimate thugs (Suge Knight).
Some of today’s artists have impressive criminal pedigrees, and their messages are often not the best advice. Are these messages what Wynton was writing about? I suspect so. But compare to GG Allin: I assume that his fans didn’t really take the lyrics seriously and destroy their lives. But does some of the lyrical content of rap actually take lives, in the sense that it sometimes encourages criminal behavior in young people? I don’t know, but I suspect so.
I was almost going to post a Vanilla Ice video but felt ashamed, so I will redeem myself with what seems to be solid advice about the music industry.
