Rihanna vs Leona who wins vocally? Jennifer Lopez vs Leona who wins vocally? Amerie vs Leona who wins vocally? Keysha COle vs Leona who wins vocally? Very and I mean Very Comparable with the likes of Christina Aguilera's two powerhouse albums, in the form of Stripped, and BAck to Basics. And the only other one I'm thinking of is Melanie Fiona. Much Props to Leona!
