I don't know why a lot of people think Thrillerwas his best song. I think his music video for the song kind of escaladed its popularity,so it is his most popular song,but not his best. Contradictory to what I formerly said, Billie Jean was his best song,and Beat It was his second best.
MJ was a great talent,musician,dancer,artist,and performer, it was just unfortuneately overshadowed by his personal life. Forever the King of Pop. Listening to Billie Jean right now.
