I think black female music artists just ain't poppin like that for some reason (your guess is as good as mine). Of course we have Rihanna and Beyonce because they've already been here for a decade + but outside of that there's nothing. You might get a hot single or two from a new one every now and then like Sevyn Streeter and Tinashe but that's about it. Let's look at the current Hot 100 the only black female artists on it currently are Beyonce and Rihanna (surprise surprise), some new Canadian-Ethopian chick named Ruth B (
) and Dreezy (with a Jeremih feature and likely one hit wonder). Where as black male artists there's Drake, Desiigner, Kevin Gates, Jeremih, Bryson Tiller, Flo Rida, OT Genesis, Young Greatness, Future, Belly/TheWeeknd, Yo Gotti, Fetty Wap, MadeInTyo. That's 13 artists and notice they're all relatively newer artists that debuted within the last 5 years, none existed in the mainstream prior to 2009. This is a trend I've been noticing for years now.
