Query: No enchantment

There's no enchantment here. The shaky tone of Charlotte Church just indicates that she's running into vocal difficulties. As a result, she has to concentrate on trying to reach the notes instead of giving expression to the music. Her interpretations are thus failures. Besides some light Christmas carols, I don't think her voice and her technique are suitable to any other thing at this stage. She should really be careful of her own development. Otherwise, she will have to bear the risk to losing her voice soon.
