The researchers conducted two different studies, one of which found that participants who wanted to improve their mood did so after listening to cheery music. However it did not work on those who did listen to the same music but made no attempt to improve their mood.
In the second study, the participants underwent two weeks of lab sessions where they were made to listen to positive music and reported feeling happier than before they had joined the sessions.
"Our work provides support for what many people already do — listen to music to improve their moods. Although pursuing personal happiness may be thought of as a self-centered venture, research suggests that happiness relates to a higher probability of socially beneficial behavior, better physical health, higher income and greater relationship satisfaction", lead author Yuna Ferguson said.
