Blondie's 'Rapture' reached No.1 on the Billboard Hot 100 on March 28, 1981, becoming the first chart-topping single to feature a rap section. Debbie Harry's rap name-checked hip-hop pioneer Fab Five Freddy and graffiti artist Jean-Michel Basquiat. The song introduced millions of mainstream pop listeners to hip-hop elements for the first time, bridging the downtown New York art scene with Middle America's radio dials.
