no shade but I genuinely believe Rihanna doesn’t hit any of these criteria and I’m a fan. She and her management struck the scene while the iron was hot. While she is undeniably talented, but she doesnt do choreo often (at the beginning and end of her musical career), she doesn’t write her music often either (her most played hits were written by friends and independent songwriters), and she doesn’t have the best live voice (compared to the powerhouses listed in the diagram).
