Guy, Bobby Brown was a REAL street nikka and he was an innovator, not an imitator.
That's different than Chris Brown, Frank Ocean, and all these p*ssy ass nikkaz who aint never been street nikkaz acting all hard and shyt.

cursing in R&B is absolutely fine depending on the context and whether or not is sounds forced. Curse words exist for the same reason any other words do; they express something that no other word can.
And cut the cute "2 parent home" shyt. The reason why you and others struggle to conceive of R&B alongside the profane has more to do with conflation of religious motifs with secularised music than anything else. R&B to a large degree was born in the church and still to this day a lot of singers learn their craft singing in choirs.
It follows on from this and the dominant role that Christianity plays in the black community, that a level of wholesomeness is expected from R&B artists and over the decades only a minority have found success by going against the grain in this regard.
And please, don't bring half baked notions of morality into this. The contradiction of thinking that it's ok for kids to listen to songs about infidelity, troubled relationships with overt sexual references as long as there's no swear words is ridiculous and self-deceiving. The idea that one night stands are particular to more modern R&B is clearly :ducktales: and I'm sure you've heard enough R&B to know that's true.
R&B has co-mingled and been shaped by all kinds of music over the years. From hip-hop to trip-hop, dance to funk etc. All this has had a secularising effect and pushed the genre outward. The lines are a lot more blurry than they once were and artists have more room to experiment. It may not be as nakedly popular as it once was (nothing really is) but great, original music is being made. It's just a matter of knowing where to look.
Are you fukking kidding me?
Most pop music didn't have cursing in it.
Most of The Beatles, Rolling Stones, Beach Boys, Madonna, Michael Jackson, etc. . . songs didn't have cursing in them.
Even most rock and heavy metal songs don't have cursing in them. They use them sparingly.
Hip-Hop is the first genre where you have most people cursing all over the place, and even that is not how Hip-Hop started up.
Run-DMC, Eric B. & Rakim, Public Enemy, etc. . . all only cursed sparingly.
It wasn't until NWA, Ice Cube, Ice-T, and the 2 Live Crew blew up did most Hip-Hop songs use heavy profanity in them and still get played on the radio, MTV, BET, etc. . with just the profanity edited out.
So, you're wrong on all levels.
In the post-NWA world, cursing is just a part of Hip-Hop, but it's lame in R&B for the most part. There's points where it works, but mostly R&B is about getting close with ya lady friend and chilling, whereas Hip-Hop is about gritty reality, which is why it works so well in Wu-Tang Clan records and sounds so contrived in R&B records.
