In 1997, two composers created ‘The Most Unwanted Song’ by issuing a public opinion survey and compiling all the lyrical and musical elements that most people found annoying. It combines a harp, accordion, out-of-tune children singing about Christmas and Walmart, high-pitched flutes, tubas, keyboard demos, someone yelling random political terms through a megaphone, and an operatic soprano rapping over cowboy music, bagpipes, and screams. It’s 22 minutes long. Source Source 2
