it is good you are not listening to the music you say makes you sad. Music has always been a passion of mine, i taught classical music for a few years. There is such a thing as music therapy and it takes years to become a certified therapist. I think it would deal with emotions too. Music can for me change how i am feeling but i have to be in the mood for some music. sometimes in the middle of the night i will listen to the radio and keep changing the station as i need to hear a certain kind of music or not good luck!
