A few guys gathered some data about people’s least favorite music and lyrical subjects. They found that the most undesirable elements of music included holiday music, bagpipes, pipe organ, a children’s chorus, cowboys, banjo ferocity, harp glissandos, oompah-ing tubas and much, much more.

The song was specifically engineered to sound unpleasant to the maximum percentage of listeners. It’s pretty bad, but although it will never be a chart topper it’s not that bad. Read more here.
