I feel you and I won't ever knock somebody for preferring 90s rnb over previous eras. It was top notch. However, when I think of peak R&B, I think of Off the Wall, Earth Wind, Fire, Debarge, Luther. Just look at the variety. You got your mainstream shyt with MJ and Debarge. You got your conscious, soul moving shyt in EWF then you got your crooning, tear jerking ballads in Luther.
In the 90s, you kind of started to lose that variety. Everybody was kind of on that same type of style: jodeci, dru hill, silk, blackstreet. Not much difference between these groups.
Look at the women: SWV, Xscape, En Vogue, Destinys Child, 702, Blaque. Again, not much variety. Formulaic.
The industry started eliminating individuality. That's why I loved that small neosoul transition we got in the early mid 90s. Sade, Tone, Toni Tone, D'angelo, Erykah etc. It was a breath of fresh air because it was creative, exciting, odd and fundamentally black. No white influence.
These days, you don't have none of that shyt. Nobody's pushing the art forward. Nobodys being innovative. I mean, yeah drill rap is "new" but it's trash. It doesn't push the art forward. It actually holds it back.
