I just think her voice only suits the type of music she uses to make. The moment she sings something different it just doesn´t work (although the idea of this concept album is good at this stage of her career imo). For example when she has tried to sing the National Anthem (proving she´s not a vocalist on true greats/divas level like Whitney, mariah, Celine, etc) or when she recorded her Xmas album last year (it just sounded boring and unispired, out of place, compared to Xamas albums by so many other artists, like Mariah or Celine themselves, or even last years Leona Lewis Xamas album was so much better). She needs to stick to her hip hop-R&B-soul style or whatever it´s called and that´s it. Not everybody can be an extraordinary singer or musician who can do it all.
