Hey, I'd say don't listen to angry songs. I used to have mad anger problems when I was younger and they got me into lots of trouble (fights, etc.). Also, I was big into real punk rock (not this new school MTV BS) at the time and I found that the music seemed to act as a vicious cycle. Although I identified with that music the most cuz I was angry, it also fueled my anger; so, it just ended up being cyclical. The more I concentrated on hip-hop that I liked (here I exclude most gangster rap), I found that the beats seem to chill me out. Or if that isn't working, make some angry ass beats, I think that will help release the energy more than perpetuate it, which I feel listening to other people's angry songs will do. If you don't like any of those ideas, I'd say listen to Cage, Ill Bill, Necro, Buck 50, or others along those lines. Cage's "Suicidal Failure" would probably be a good one. And get mad lifted, that should chill you out.
