Oh okay, so you do like her. I have this friend who doesn't like her singing at all and always calls her a man and says she has the same vocal range as Sinatra. I could go either way, but am usually indifferent to her voice. I don't quite like her style, though.

Oh I'm anything but indifferent to her voice or looks! That Elvis is one lucky bastard!
