The shortest song in the world is just 1.68 seconds long - Apparently.
The song, "In Heaven," was written and performed by British musician Brian Hodgson in 1967. It was recorded as part of a larger work, "The Pleasure World," but was eventually released as a standalone single in 1968. The song's brevity was reportedly due to a production decision to create a sense of urgency and anticipation. Despite its short length, "In Heaven" has been recognized by the Guinness World Records as the shortest song in the world.
