Daisy Bell was written by Harry Dacre in 1892 as a cheerful popular song about a bicycle built for two. It later became famous in technology history as the first song performed using computer speech synthesis in 1961, an association echoed when HAL 9000 sings it while being shut down in 2001: A Space Odyssey. That scene linked the innocent tune to failing machines and quiet menace, inspiring countless slowed, echoed remixes online that lean into its accidental horror quality.
