We all listen to music when we're in an angry or bad mood, so my question to you is what as in genre and which artists are you generally listening to in those moods? You don't have to answer my question, but I'm interested in what you have to say.
If I want to just relax to something because I'm stressed out I usually go for some ambient (ex. Stars Of The Lid) or modern classical (ex. Peter Broderick, Dustin O'Halloran). Now if I'm just really pissed off and I want to listen to some pissed off music I go for noise rock like Big Black, Jesus Lizard, Shellac, and Lightning Bolt. Below is a song that I think is a pretty nice pissed off song.
