Music is a powerful tool to get in touch with your feelings. I find it cathartic to really let myself be immersed in sadness/happiness/anger (or any other feeling) through listening to music. Whatever you are going through at any given time, music helps. It just does. Music can also be used as a tool to consciously change your mood – by simply changing which tracks you listen to, you can shift your mood from sad to a little happier. I find that absolutely fascinating. 

Vältra is a fictitious app that lets you find music based on your current mood – or how you want to feel.

(If you, like me, have over one hundred playlists and a tendency to forget song titles, you might find it quite useful – and a real time-saver.)
