Britney Spears. Yes, I said it. Why? Because if you listen to her voice, I mean REALLY listen to it, she has one of the most beautiful voices ever. It's hard to describe, but it's very soothing, soulful. Of course, most people don't know this because they haven't taken the time to listen closely to one of her better ballads or "hear through" the bells and whistles on many of her up-tempo hits.
