First of all, do you even know which country the video comes from? And, how do you figure something is "almost legal"?

Second, taste in vocals is quite subjective and largely influenced by what one is "used to", or conditioned to like. If you do not like the quality of her voice, you are entitled to that opinion. But from an objective standpoint, she has good pitch accuracy and rhythmic timing. I'd rate her a fine singer myself.
