Maybe I'm wrong but I think that this is a core issue amongst the older heads. I'm an older head myself and this irks the hell out of me. Anytime quality hiphop/talent/lyricism is brought up, the word "dig" has to be used. We have to "find" rappers who actually.......RAP

and meanwhile, cats who LITERALLY say that they aren't rappers (Lil Yachty) get the most shine and are FORCED down the masses throats.
What this has done is give up and coming rappers little to no incentive to actually RAP. They see these mumble, elementary, ABC type rappers getting all the fame, fortunes and IG models and they say "I want that too

". So a dude who might can be the next Nas dumbs himself down to fit in with what's popping on the radio (and yes radio exposure helps ALOT contrary to what the coli says).
This same thing has happened in R&B also. There's little incentive to making REAL soulful R&B anymore and REAL singing, so young up & coming singers follow what's being played on the radio: this hybrid rap-singing over trap beats featuring the hottest in the moment rapper
Just my take on it. I just wish there was more balance as far as actual talent getting the opportunity to have a mainstream look.
Back in my day cats like Mos Def, Talib Kweli, Canibus and even Pharoah Monch could be heard on mainstream platforms.
There was BALANCE.
