I agree with you fam, today's RAP music is terrible. It's not hip hop whatsoever. It's mainly mainstream as you stated. When the big wig record labels started to infiltrate hip hop, their agenda was to destroy it and dumb it down to the masses. Mind you, hip hop just came out of the disco era which destroyed the efforts of the work the elders put together in the 1960's trying to uplift our communities. When they started the disco era and pimp movies, our agenda to uplift change. Then came the crack era....But, out of that era came something that this government didn't intend to which was hip hop. It was a culture where you took your struggle and chanted to the world. Then you had your Melle Mel's, Public Enemy, X-Clan, KRS-One, Channel Lives, Brand Nubian, Ice Cube, Pacs..etc of the world that came in and was telling folks this is the way it is. Forget those sit-ins, we're taking our freedom. This was a big difference from the 70's era when the status quo felt they finally destroyed our power.
It's funny because growing up, my parents wouldn't let us listen to hip hop. My older brother is 7yrs older than me, he would sneak and listen to hip hop music. Mostly what ppl consider today to be conscious hip hop. The way the music is today, I wouldn't dare let my children even listen to the radio. That's why I'm glad that my father was throwing instruments at us because it mold us into something different. I was born in 88 and we're probably the last generation to experience the golden age of hip hop.
There will be no change until all these major labels are no longer profiting from us. Back in the early 90's, there were mostly only indie labels. Now the elites feel they are ahead of that wave because of distribution. But, the way it's going now, these young MC's are getting themselves hot off the internet and they can basically sell their music through there own channels.
I'm starting to see a change in hip hop, but mainstream will continue to be mainstream. Just to bad the kids live by it through every song and lyric.
