Most Popular Music Styles 1910 - 2019

Timeline history of the most popular music genres and styles from 1910 to 2019. Historical popularity is based on worldwide vinyl and CD records release frequencies for specific genre adjusted to recent years music charts. Numbers are relative to each other to reflect popularity change throughout the years (it's not a percentage). I've tried to use sub-genres in most cases to present as much as possible diversity.

Hat tip to Denis Safiullin, who alerted me to this idea.
