The Spice Girls' debut hit, Wannabe, is the catchiest UK hit single, an online experiment has suggested.
Participants recognised the song in 2.3 seconds, compared with an average of five seconds for other popular hits.
Researchers developed the interactive game, called Hooked on Music, as part of a scientific study to unlock the secrets of what makes music memorable.
The initial results from the study will be unveiled at the Manchester Science Festival on Saturday evening.
Data from more than 12,000 participants was collected from the online experiment, which was developed by the Museum of Science and Industry (Mosi).
People who played the game were asked if they recognised a song, which was randomly selected from more than 1,000 clips of best-selling songs, dating from the 1940s until the present day.
The Spice Girls' debut single, which spent seven weeks at number one during 1996, was the most quickly recognised song by participants, taking an average of 2.29 seconds.
