Music is a mood altering non substance.
Feeling down, depressed, sad?
Music can enhance you mood.
Ask your doctor if music is right for you as it may be addictive and have some side effects.
Side effects may include head bobbing, foot tapping, finger snapping and persistent melody flashbacks.
There may be others but the fact that it can made you feel happy and upbeat is a very good reason to use it.
Caution: Stay away from depressing or angry music.
So start singing a happy tune and see how you feel.
