What makes those songs violent? From what I've heard it's just loud, not necessarily violent. I don't think any song can be called violent unless they're talking about violent things as the lyrics.
i listen to disturbed, system of a down, ocasionally slipknot and the whole bunch, but i never feel aggresive
Ok this is going to be weird but if you ever heard christian metal I think Hurt is one...I disagree with the whole Metal makes people violent thing...It is only the people that listen to it that gets into a rage. I listen to Metal all the time and no anger at all.
