The shortest song in the world is just 1.644 seconds long - Apparently.
The song, titled "Nanga Danga," was recorded in 1963 by a British band called The K-Tels. The song's brevity was likely a marketing stunt, as it was included on a EP titled "Naga Danga" alongside four other songs, each with similarly absurdly short runtimes. The record has been verified by the Guinness World Records as the shortest song ever recorded.
