‘Mahna Mahna’ by The Muppets
This one takes the cake as one of the most annoying, nonsensical songs on this list. The lyrics aren’t in any existing language, so the listener is left wondering what’s going on.
It’s a battle of meaningless jabber and melodies, like “Doo-doo-dee-doo-doo, doo-doo-dee-doo.” Repetitive melodies like this one never get very far (via Mental Floss).
