Obviously Adele and Taylor sell more than Beyoncé, but there is a type of power that Beyoncé has where she's able to spark massive discussions. It goes beyond peoples just buying her album. It also comes from being in the game for nearly 20 years and being talented, adele and Taylor are still in the parts of their career where they could really disappear. It's unlikely but we've seen it happen before. Beyoncé isn't going anywhere even if she has five flop albums.
