The Jackson 5 weren't even in the Top 100 of hits of the 1970's!
You’re right! I only looked at 1970, not the whole DECADE. I was only 10 that year - I was too busy huntin’ squirrels with my BB Gun to listen to the radio much. ;)

Well, that’s a list of “Top 100 Rock” songs, and the Jacksons were R&B, not Rock.
