I hadn't known about him before reading his Wikipedia page, just now. And I tend to read a lot :-)
Ask a few random folks of various ages, on the street. Check out YouTube views for some of their videos, weighted by decade (videos from the 80s with tens of millions of views can be considered as popular as stuff with high hundreds of millions now). Album sales. Chart rankings from multiple countries. Endorsement revenues.
