Query: Worthless Vocals

Britney might win the young crowd over, but for anyone who has any clue about her singing talent, she is old news. With each album she does, her vocals get weaker and weaker. Take away the background vocals and all you would hear is a very weak, nasal sounded duck. I have nothing against Britney, but her vocals are terrible. She covers herself up with background singers and lets them do all the work. If you see her live, you can't even hear her sing, her microphone is turned down twice as low as everyone else who sings. I don't know what has happened to her voice, but it does not even compare to Avril, Pink or Christina.
