I have a job that I don´t really like and so I am angry and frustrated many times. I don´t think and don´t agree that music affects the mood in being angry. Ok, some happy music can help to be in a happier mood and some sad music is not good if you´re already sad. But I don´t get angry if I hear metal or any faster music.
What to do against being angry? It´s not easy but the only thing that helps is to think about it and try to relax. I know from my own experience that it´s not easy at all.
