Does listening to metal have any negative effects?

[unity100]

Metal generally tends to have a lot of pent up angst and rage. And in numerous cases (especially some bands) tend to make songs about rage and destruction, 'spectacular' end of the world scenarios (ragnarok etc), or songs that praise and elevate hierarchical schemes of dominance (kings, emperors, lords, warriors). These concepts are negative in their core.

At least this was from the time i listened to metal.
