yeah, they are KINDA forced to follow the bullshit becasue of the record label pressure, but you can still singing a song ala Omarion's new shit without cursing, in fact you can sing about butterlies and shit and get a verse from Schoolboy Q. Even tho ratchet R&B is the lane that someone signed to a major label is guided to go, there is still a commercial empowering lane(Janelle, Alicia keys), so anyone can go there.

a male singing can sing about sleeping around and use his vocal range, and have some melody, and not talk about champagne and cars.......and sound good.

curses, lack of vocal range, and lack of melody is what the problem is.......but even if you fixed one of the three, you can still be better than whats on the radio now.
