A university professor in London with a PhD in music psychology claims to have cracked the formula to creating a happy song.  (???)  Basically the song has to be in a major key, with 137 beats per minute, and other musical technicalities.  Oh, and dance-ability is a must.

Here are the Top 10 songs that follow his formula:

1.  “Good Vibrations”The Beach Boys

2.  “I Got You (I Feel Good)”James Brown

3.  “House of Fun”Madness

4.  “Get the Party Started”,  Pink

5.  “Uptown Girl”Billy Joel

6.  “Sun Is Shining”Bob Marley

7.  “I Get Around”The Beach Boys

8.  “Y.M.C.A.”,  Village People

9.  “Waterloo”ABBA

10.  “September”Earth, Wind & Fire

The guy who came up with the formula even teamed up with some musicians to make the perfect happy song.  It’s called “The Lighter Note”, and you can check it out on Soundcloud.
