Not that Beyonce is as much as her Hive claims she's an all-time GOAT, she's clearly better than Amerie and Keri. Not saying blackballing isn't a thing, but she didn't need to do it for them... they didn't have the songs or the "it" factor.
Beyonce has the total package and a superior voice (It's a 7 of 10 if im being generous). Only people who could compete in her lane were Aaliyah, Rihanna, and Lizzo; they definitely have the hits. But Aaliyah has a weaker voice and died, Rihanna isn't really in Beyonce's lane and has a weaker voice too, and I think Lizzo is under Beyonce's wing if she doesn’t self destruct before she hits that level.
