Did Billboard Music Get It Wrong?

Nicki Minaj was named "Greatest Female Rapper" of All-Time. Did they get it right? I have my top 3 female lyricist (including Minaj) plus a fan favor 4th. Now I already know some Barbs might come for me. I enjoy Nicki as a female rapper, but not the greatest. I also have a prediction for who got next. Listen to my line-up and see if we agree or disagree. Again, this is solely my opinion and no one else's. Let's get it!
