'Say Say Say' most popular Jackson song: Billboard

Michael Jackson had dozens of hits, but his most popular one wasn't a solo smash or a tune with his brothers. It was a song with another icon.

Billboard says "Say Say Say," his 1983 hit with Paul McCartney, is the most popular Jackson song. That was followed by "Billie Jean," the Jackson 5's "I'll Be There," ''Beat It" and "Rock with You."

"Billie Jean" was at No. 1 for seven weeks, while "Say Say Say" held the top spot for six weeks. But the McCartney-Jackson hit stayed in the top 10 longer.

Billboard is releasing Jackson statistics ahead of the anniversary of the King of Pop's death. He died June 25, 2009, at age 50.
