Both the short and long answer today is HELL NO! As many talented rappers out there who are in complete control of their pen, can't write a clean rap or won't have a career if thats all they rap about was just clean. sure there are always the one rapper here or there but the majority can't and won't do it even though they write their own shit. The care more about the streets instead of the masses and that's why they can't do it. Heavy created his lane and never left his lane and it worked for him. It's the same argument with clean comedians. They are the exception, not the norm. If you listen to famous, big time comedians without the profanity, you will there there is not much to their body of work after all.
I disagree, that Lil Baby song with Kirk Franklin was a banger. As with 90's hiphop as long as it has a nice beat and a hook/chorus to latch onto......it's a go.
Heavy had energy, lyrics and style.....
So no a Carlton type won't work.....but say if Da Baby circa '18/'19 had come out with the same gimmicky videos, bass bumping beats and "clean" or more radio friendly lyrics... I think it could work......dude's problems aside.. ..he had "it" for a minute.
Every era had the "clown" but not a clown rapper. Busta, Missy ....etc Da Baby picked up that baton.
There are quite a few of these younger rappers out now that could be clean, but they worry about going back to the hood and their rep....etc
Worry about stsying positive, stylish, getting the bag and hood love will come as long as you have real ties to them, and not some fabricated or financially dependant connections.
