Plain and simple, Gen-Z and Millenial producers didn't have church upbringing musically and that is what has crippled R&B....
Now it literally is chopping up 90s samples and adding some Trap drums with a horrible out of key vocalist sounding like they are having a stroke when they sing...
Producers have no musical understanding, no Devante Swing, Teddy Riley, Timbaland, Babyface, Stevie Wonder...
Metro Boomin? Ha ha ha....
R&B is in horrible shape today....Only dude that even brings a level of groove is B Mars, he is at least trying.....
