It was a good long while between the time I first heard JoJo on the radio and when I finally saw her in a music video. During that time, I had assumed JoJo was black. Yes, I know it's bad to assume, but her voice was so soulful that I didn't think it originating from a tiny white girl. So I knew the truth, but the truth was too little, too late. JoJo was black in my mind for such a long time that I don't feel bad including her on this list... and if you don't like it, you can get out (leave!), right now.
