Spice Girls Science: 'Wannabe' Makes History As Catchiest Pop Song In 'Hooked On Music' Project

It may not compare to the invention of the wheel, but scientists say they have discovered the catchiest pop song in history -- and it's a spicy revelation. "Wannabe," the debut hit from "The Spice Girls," was the most easily recognized song on a list of 1,000 pop tunes in a yearlong study by the Museum of Science and Industry in Manchester, England. Using an online test called "Hooked on Music," researchers asked some 12,000 participants to identify hit songs from the 1940s to the present day.
