Paul Simon wrote The Sound of Silence, first released by Simon & Garfunkel in 1964, and its opening line, 'Hello darkness, my old friend,' has become one of the most recognisable lines in popular music. The song gained wider fame after an electric remix reached number one in the United States in 1966, and it has remained a cultural shorthand for quiet reflection ever since. Online, creators reuse the opening as a dramatic cue for sad, lonely or ironic moments, often pairing the familiar melody with late-night scenes, unexpected twists or nostalgic footage.
