The shortest song in the UK Singles Chart is only 1.644 seconds long - Apparently.
In 1962, British musician Ray Stevens released a novelty song called "Zip Zip", which held the record for the shortest song in the UK Singles Chart. The song's brevity was reportedly due to a miscommunication between Stevens and his record label, who thought he was joking about the song's length. Stevens' record label, Pye Records, officially recognized the song's existence, and it charted at number 16 in the UK Singles Chart.
