Harry said that "'Heart of Glass' was one of the first songs Blondie wrote, but it was years before we recorded it properly. The song was re-recorded in a second demo with the same title in 1978, when the song was made a bit more pop-oriented. This original version was inspired by The Hues Corporation's hit disco song " Rock the Boat" (1974). For this reason the band referred to it as "The Disco Song". The song had a slower, funkier sound with a basic disco beat. This earlier version was initially recorded as a demo in 1975.

Background ĭebbie Harry and Chris Stein wrote an early version of "Heart of Glass", called "Once I Had a Love", in 1974–75. Harry and Stein sold their future royalties to the song, and the rest of Blondie's catalog, to Hipgnosis Songs Fund, in 2020. Harry herself stated that "Heart of Glass" was, along with " Rapture," the song she was proudest of having written. It was inducted into the Grammy Hall of Fame as a recording of "qualitative or historical significance" in 2015. "Heart of Glass" ranked at number 66 in the UK's official list of biggest selling singles of all-time, with sales of 1.32 million copies. Slant Magazine placed it at number 42 on their list of the greatest dance songs of all time and Pitchfork named it the 18th best song of the 1970s. It was ranked at number 259 when the list was updated in April 2010 and at number 138 in their 2021 update. In December 2004, Rolling Stone ranked the song number 255 on its list of the 500 greatest songs of all time. It was featured on the band's third studio album, Parallel Lines (1978), and was released as the album's third single in January 1979 and reached number one on the charts in several countries, including the United States and the United Kingdom.

" Heart of Glass" is a song by the American new wave band Blondie, written by singer Debbie Harry and guitarist Chris Stein.
