I’m not even a Beyoncé fan, but bro, don’t play yourself. Amerie can’t sing. At all.
“Just one thing” was a nice tune when it dropped, I’ll admit that.
But Amerie has never been anything but “a pretty face with a thin voice that benefited greatly from slick production”. Slick production is exactly what “Just one thing” was.
Her style that people claim Beyoncé bit wasn’t her style. It was her producers. And her producer did a hell of a job making her sound tolerable over her tracks.
