Having a bad day ? Listen to some Billy Joel! (one of our favorite artists!)   Want to know the happiest sounding songs?  A university professor in London with a PhD in music psychology claims to have cracked the formula to creating one.  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 5 that meet his criteria.

#1 “Good Vibrations” by the Beach Boys

#2 “I Feel Good” by James Brown

#3 “House of Fun” by Madness (huge in England),

#4 “Get the Party Started” by Pink, and

#5 “Uptown Girl” by Billy Joel.
