I don't think that Beyonce's was the best voice of DC. Kelly has the best voice (the quality and tone of her voice is far better than Beyonce's). Beyonce is the more uninhibited singer (she never holds back and she knows how to run and rift like the best of them). Both women can sing but Beyonce's voice is to abrasive at times and she often sounds like she's shouting. Kelly's voice is as smooth as silk,yet she has power and range but she holds back ALOT. As pretty as her voice is she doesn't always sing like someone who has been apart of this business for over ten years,sometimes she sounds like an amateur;which is not cool for someone who has been apart of the industry for as long as she has. However,her VOICE is still BETTER than Beyonce's.
