The way you look at courting, relationships etc colours the way you listen to the music. The term grown folks music wasn't just for fun,it was a way to keep the subject matter and approach for an adult audience that was the main demographic for R&B. You can tell by the way the music is approached now that there is an understanding from a technical musical standpoint ,but far as maturity and creating music that speaks to that complexity of love/relationships while writing from not just a sexual viewpoint is harder to do and requires more then just cursing and breaking down your engagement with women to fukkin..that's why eventually we return to the classics,they just don't make em anymore.
