According to my personal experience,music has a more positive effect on our life.When we are in a blue mood,we could listen to some foreigner song.Such as,My Love,the Funeral of Hearts and Close to the flame etc.The music is that we needn't to realize what are they singing.When you listen to their rhythm and style,you will feel your heart be touched and shake in a blue mood.Then,you will be enlightened and acquire power.
