Wow, just wow.

I love watching the expressions of the judges. At about 4:01 Simon exhales right along with her. She's good, really good, what an ear, great range, she interprets the music well, phrasing is beautiful and judging from the judges expressions I think they got it just from the way she held the mike "this may be good!" and then that first note. "yes!"

The only musical gene left for me from my opera singing paternal grandparents (my brother got the genes and some were left for my sister, Duck on Wheels) was perfect pitch.

Her every note is spot on. But you can have an ear and still be bad and she is wow, just wow.
