Feel Good Songs 2
I’m creating a list of songs that make you feel energized, inspired, and put you in a positive mood (hence -“feel good”). As a DJ, I’ve noticed there are certain clues if a particular song is a “feel good” song for an audience – tapping of feet, snapping of fingers, clapping, singing along, and whistling (usually done subconsciously after the song is over). In addition, a feel good song doesn’t have to be “danceable” (although it can be), and it doesn’t even have to be upbeat. So, which songs make you feel good?
