It's a song especially made to be the worst song in the world based on public opinion. Including the most disliked instruments, song length, and song styles.
It includes an opera singer rapping about cowboys to a Tuba while a Bag Pipe plays. Also, a chorus of children singing about shopping at Walmart. There's also protester yelling into a microphone, random changes into tempo and strange lyrics. Among other things.
The description made me finally bother listening, but it didn't really annoy me that much – probably because I already knew it was meant to be irritating.
I'll try setting it on some unsuspecting friends one day.
