The shortest song in the world was just 1.316 seconds long
The song, titled "They're Coming to Take Me Away, Ha-Ha!", was recorded by Napoleon XIV in 1962. The novelty song features a repeating melody, with the singer's voice being a key part of the instrumentation. The song's brevity was a result of the singer's decision to use a recording technique that allowed him to sing over a pre-recorded backing track. The song still holds the Guinness World Record for the shortest song.
