In 1977, iconic R&B singer Marvin Gaye finally caved to pressure from his record label to record a disco song. Gaye, who wasn’t fond of the musical genre sweeping America, set out to make a disco parody. The result was “Got to Give It Up,” which not only wound up reaching the top of the Billboard Hot 100, but also became an inspiration to Michael Jackson and a host of other major artists. “Got to Give It Up” hit No. 1 on the Hot 100 49 years ago today, June 25, 1977.
