I am aware of this...you could say this about a few other r and b artist. In the end, people did not buy her albums. That's not Beyoncé's fault, it's the people who choose. Also, is Rich not allow to produce for other artists, the go go R and B mix is his style? He produced for Toni Braxton, is it her fault too? Her career just didn't take off. It is what is

.
no one else was going the gogo style sound at the time on a national scale besides amerie and rich. and then beyonce hopped on it. shes allowed to do anyone's style but audiences are also allowed to notice the swagger jacking in the same way jay doesnt not get credit for big's line just bc he is more popular now
it kinda is beyonce's fault (and other artists who use this same methodology) if her team is paying to dominate radio, tv, etc and push other people's content down/out if they may not have the same money/industry clout to compete in those rooms. from there the audience isnt deciding, its the labels forcing through money. its not like amerie wasnt popular or didnt have her own lane going successfully. her sound literally was stolen
"one thing" was the soundtrack single for "Hitch", one of the biggest summer blockbusters at the time. her career was going.
This is the only isssue I have with your post. Alicia keys was a new artist and her first two albums were big
alicia was just as much of an anomaly then as beyonce is now.
5 grammy's on your first album is not normal and is a rarity, way more than exceptional for a new artist, that even rihanna does not have the pleasure of bragging about even with her success level.
