I often get angry when things don't go as planned or when I have to be in a real rush. In moments like this, good old rock and punk are my best cures for bad mood. Loud heavy music helps me to throw out negative emotions and calm down. This has worked well for me since my teenage years. But if before I just turned on the music to the max in my room, now I use headphones for this. I was really looking for how to boost bass on headphones for such situations.
