Negatively Charged Musical Experience

So this group is kind of experimental. It's a music group, but isn't limited to any one genre, but is limited to music that releases negative emotions; sadness, hatred, anger, the need to harm, depression would all be examples.
So here's my theory: A common misconception of music like this, is that, such music produces or strengthens negative emotions, but the truth is that it is a healthy and safe outlet of such emotions, and the more these emotions are treated by this music, the more overall positivity can be seen.
So please, feel free to express your opinions regarding my theory, post music that you feel is "negatively charged", and please INVITE YOUR FRIENDS that you think might enjoy being a part of this.
The only rules I can think of:
Respect opinions
Debate and discuss with courtesy and respect
