You might think that only listening to happy music will make you happy, but it turns out that sad songs might boost your mood. A study done at the Freie Universität Berlin in Germany found that sad music actually evokes positive emotions. Sometimes, listening to the music helped them release and process their emotions. 

Perhaps the biggest benefit was the following: People who listen to sad music can experience grief and sadness through the music without having to deal with anything negative triggering that in their real lives.
