“Too Busy Thinking About My Baby” #4 6/28/1969

Many times, Motown songs became hits years after they were recorded by someone else at the label. This was done first by the Temptations as a 1966 album track, but Marvin Gaye made it the top-selling R&B single of 1969. Definitely a 180-degree turnabout from the downbeat nature of “I Heard It Through The Grapevine.”
