I don't know. People use to say that about Diana Ross and clearly those with less #1 then her. She outpeaked them due to popularity and was able to continue getting number 1. Once the 90's hit Areatha, Patti, Gladys gained more demand because the were better and more consistent entertainers. This is that case with Beyonce. She widely more in demand even though less popular then Rihanna.
