It's funny because Prince influenced The Love Below.I don't consume a lot of R&B outside of the early 2000s so this never occurred to me but it definitely makes sense
Again when you look at the sonic darkness on Love Below/808s and Drake basically emulating 3K/Ye and the Timbaland/Aaliyah style of dark R&B that Weekend and Frank happened to be doing in the early 2010s yea it lines up
He might be the grandfather of black music you wouldn't pigeon hole as exactly R&B
