That explosion of women rappers felt like a tech bubble. That shyt burst and most of those chicks can't sell an album or tour. What's left? Nothing, because labels were solely focused on finding the next hyper sexual hoe rapper. Ask yourself...who is the next big ATL rapper? Who is following up Baby and Gunna? Take ATL out the picture now...who is the big young-ish rapper now? Yeat? BigXthaPlug? Perhaps. It's not Ken Carson, no matter what the label tries lol. Long story short this isn't about Kdot or Drake, it's about labels not giving a shyt and a decline in artistry.
Also? Lot of kids found a more interesting get rich quick scheme: streaming. Being a rapper is officially too hard lol.
