Why does the hip hop radio only play rap song song from rappers thst only talk about females and money and nothing else from their songs?

for example they play alot of Pop Smoke butthey only playhis songs about women and suff, i k ow he has songs about the streets and being gangster but they dont play that. Lil T Jay also..he has alot of rap songs about the hood and grinding to survive but they never play that on the radio, they constantly play a song where a girls calling on his phone and he cant get her off his mind.
