"Her voice is generic!" "She's nothing"
Oh shut the hell up. I'd much rather take someone with a voice like many others that can project feelings and many sensations into their performances thus making me believe they are amazing over someone with some obscure voice that never does anything spectacular with their voice aside from sounding different.
Being vocally transcendent comes from more than just having a different voice, it's being able to exude excellence, thrill, excitement, command, etc. when you sing. Something that she does with the utmost ease and never fails at doing so because she is such an expressive performer. She'll never give any less than all she's got.
