Personally, I liked the voice of whoever was singing - it sounded good, but not perfect (as it should be). In fact, I still found her voice somewhat better than I would have expected from Elizabeth, who has not concentrated on music. It's always bugged me in movies when an "amateur" starts to sing in a professionally perfect voice (not only that, but it often sounds as if the singing was recorded in-studio, not in the real world!). However, if you don't like her type of voice (rather than the quality), that's a matter of personal taste! :-)
