Why do certain songs stay in your head, playing endlessly on repeat?

It is a recognised phenomenon. These songs are known as "earworms" and psychologists at Goldsmiths have come up with a scientific formula which describes why certain songs are catchier than others.

Dr Lauren Stewart, leader of the study, said "it is interesting to us to find out whether earworms actually have a role to play."

Terry Dobson, founder of the band Black Lace and famous for hits such as Do the Conga, Superman, and Agadoo, explained: "We just wrote the songs, played them and hoped that they would capture the imagination."
