From what I've seen only, she can at least sound exactly how she sounds on the record, live, without lip synching. I give a 7, her voice can get so annoying sometimes ("Alice" proved it).
8.5 she does not have a strong head voice, cannot hit really high notes, or hold a long note for longer then 10seconds which makes an artist a 10 in my eyes, but she does sing with emotion and her low voice is eerie amazing
