My two favorites: Carley Rose and Beatrice.
Carley because Dear God that girl can sing. If reincarnation is in any way possible, she is, because nobody can sing that well at 13.
Beatrice had me at Titanium in the Judges Homes. I kind of wish she was mentored by somebody else though as I never like the songs Britney gives her. She won't win, but I love her voice.
Agree w/ all of that. Beatrice reminds me of a young Nora Jones. She is not polished like Carly but I like her voice over the rest.
