In 1997, two composers created “The Most Unwanted Song” by compiling as much annoying music as they could possibly think of. The song features a harp with an accordion, an operatic soprano rapping over cowboy music, bagpipes and screaming, out-of-tune children singing about Christmas and Walmart, lots of high-pitched flutes with tubas and keyboard demos, and someone yelling random political terms through a megaphone. It’s 22 minutes long. Source
