Need a boost? Just put on this feel-good playlist, created by neuroscientist Dr. Jacob Jolij of the University of Groningen in the Netherlands, scientifically guaranteed to make you feel good.
Dr. Jolij analyzed songs across decades and found that "feel good" songs are more up tempo than your average pop song: "Where the average tempo of pop songs is around 118 BPM, the list of feel good songs had an average tempo of around 140 to 150 BPM." It also held true that they were all in a major key, and had lyrics about positive events.
