I really doubt finding a list of the most popular singers ever that doesnt include this man: Michael Jackson.
He literally revolutionized the music industry. According to Guinness records, M.J is the most crowned artist of all-times.
The king of pop is apparently known in all countries, and people still talk about him even after 11 years of his shocking death

I'm Gustavo Woltmann. What do you think, How is the world's famous singer?
