Heavy metal isn't supposed to be peaceful, where do you get that idea from? You might as well say there's nothing rowdy about ambient music.
What does it say about the psyche of the listener? I'm interested in psychology.

Extreme Metal Music and Anger Processing
Heart rate increased during the anger induction and was sustained (not increased) in the music condition, and
decreased in the silence condition. PANAS active and inspired ratings increased during music listening, an effect that was not seen in controls. The findings indicate that extreme music did not make angry participants angrier; rather,
it appeared to match their physiological arousal and result in an increase in positive emotions. Listening to extreme music may represent a healthy way of processing anger for these listeners.
i use music to process emotion myself but it says something about the listener who listens to heavy metal the majority of the time. They are angry and the music is a reflection of that.
