As far as I know, Mariah Carey (at her peak) and Rihanna are the biggest selling single artists out there in America. However, are they really as dominant as IU?
#1 Chart topping singles since 2010 and multiple top 10 b-sides and songs as a featured artist
Not just that. All her songs have massive longevity and easily hit perfect all kills
Is there any international artist who can relate to this type of digital success? Maybe in Japan?
