You didn't know this??
I'll never forget the random YouTube comment I saw of an aspiring rapper saying how he was pressured by his CAC record label to use more N bombs in his raps. And this was recent. If I remembered the actual video I would screenshot it and post it.
Not sure how old you are, but what you're doing here is a bit of deflecting.
NWA and associated acts blew up with very little promotion and little airplay on radio or video. They sold more units than the most popular rappers who had big label backing, promo budgets and airplay.
Ever since then, artists and labels saw that there was a big audience for that type of content and language and they used parts of that formula.
And when another act blows up and sells major units, labels try to capitalize and sign artists or select songs from upcoming albums that fit the formula.
When Onyx came out, you saw much of the next crop of artists yelling and screaming on record for the next year....for example. And talking about violent content.
Groups I mentioned came out in the late 80s and the early 90s. But the profit motive attached to catering to what the audience responds to is as old as the record business.
YouTube videos about label "paying" somebody to use certain songs on a record wouldn't be a reveal, nor would it be relevant to the thread topic, in my opinion.
Youth is always creating new slang, reinventing terms, adopting regional slang from elsewhere.
"By design" implies that the kids are just puppets being remote controlled by outside forces.
