A list of the greatest pop vocalists would seem incorrect without the “King of Pop” taking the top spot. After starting his career as a member of The Jackson Five, Michael pursued a solo career with hits including ‘Beat It,’ ‘Billie Jean,’ ‘Thriller’ and ‘The Way You Make Me Feel.’ The result? He is the third highest selling musician of all-time (trailing only The Beatles and Elvis Presley).
