In reply to Umm.

Her tone, transitions, falsetto,chest voice, vibrato and countless other things she could do with her voice negates everything you said and her live voice is more rich powerful. She was a versatile vocalist and had her own singing style ala Sade. Her tone may not appeal to you which is fine but don't try to make it seem like a fact that she was just ok when she displayed all the tools to show that she was more than just ok...no one performs at the Oscars at the age she did if they were just ok.
