Researchers at Goldsmiths University have been looking into the mathematical and physical properties (i.e. sound waves) of songs, trying to determine exactly what makes a song catchy in the first place.
In the process, they compiled a list of the catchiest songs of all time. Topping the list? Queen's "We Are the Champions."
One of the musicologists involved in the study, Dr. Daniel Mullensiefen, explains: "Every musical hit is reliant on maths, science, engineering and technology; from the physics and frequencies of sound that determine pitch and harmony, to the hi-tech digital processors and synthesizers, which can add effects to make a song more catchy."
Other songs near the top of the list included "Y.M.C.A" by the Village People and Europe's "The Final Countdown."
