Solange should have been on the list
Monica and Mya and Kelly too

Sade is a soul jazz singer

Beyonce should have been top 20 not top 10 and only because of her achievements and longevity but not artistically.

Aaliyah should have been on top 10
Artistically, Quality of her albums, Unique voice, unique style and image, INFLUENCE, all her albums changed the game every single time! And she was a real R&B artist with real R&B albums that were 10/10 or 9/10. Beyonce doesn't have any R&B album that is even a 6/10 her best work in R&B was with DC and it was singles not albums.
