Spice Girls' ‘Wannabe' Named Catchiest Song Ever By New Study

In a finding that's sure to ignite debates among music lovers around the world, researchers say they've identified the catchiest song of all time.

The winner: the 1996 Spice Girls hit "Wannabe." (Try getting that out of your head now.)

Researchers from the University of Amsterdam worked with the Museum of Science and Industry in Manchester, U.K., to figure out why some songs are catchy and others are not.

"You may only hear something a couple of times yet 10 years later you immediately realize that you have heard it before," Ashley Burgoyne, a computational musicologist from the University of Amsterdam, told the BBC. "Yet other songs, even if you have heard them a lot, do not have this effect."

So what makes a song catchy? It's not simply your ability to know it and recognize it. It's how the song stays in your head even when it stops playing -- the so-called earworm effect.

To measure this, the researchers developed a game. Because they're measuring "catchiness," it's not your typical name-that-tune type of arrangement. Instead, you hit the stop button the moment you recognize a tune, and then the game tests the ability of the song to keep playing inside your head.

It's called Hooked on Music, which you can actually play for yourself right here. Warning: Your productivity for the day will plummet the moment you click on that link. Then again, how often do you get to participate in real science?

The game used the top 40 songs from each decade over the past 70 years. Of the 12,000 people who played during the yearlong study period, the Spice Girls track was tops, recognized in an average of 2.29 seconds.

And while the game may seem silly, there is a very serious purpose behind the study. The researchers wrote on the game's website that they hope to use the results to further research into dementia and Alzheimer's disease.

1. Spice Girls, "Wannabe"
