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
