What is the shortest song?

The shortest song ever commercially released is "You Suffer" by British grindcore band Napalm Death. The song lasts just 1.316 seconds long and consists of a single, guttural scream of the lyrics "You suffer, but why?" It was recorded in 1987 and holds the record for the shortest recorded song according to the Guinness World Records. Despite its brevity, "You Suffer" has become somewhat of a cult classic and is often played live by the band as a joke.
