Let's Get It On was released by Marvin Gaye in 1973 as the title song of his album of the same name, becoming one of the most recognisable soul recordings of the decade. Its smooth groove and intimate mood made it a lasting shorthand for romance in film, television, and later online video. Instrumental versions began circulating on soundboards and editing libraries because creators wanted the atmosphere without the vocal, letting them score reveals, montages, and parodies. That flexibility is why the instrumental still appears in memes and short-form edits today.
