Heavy metal for kids?

Is Heavy metal harmful for kids under 5 years old? Please submit your opinion in the comments. I think that heavy metal is maybe not the best musical style that a kid should listen to because the lyrics of the songs are usually violent. Though if that infant knows to make the differennce between a song and reality, there is probably no risk that he become violent. Doesn't matter what the musical style of music your child is listening to, don't let him listen to it at maximum volume. THIS can probably get your kid violent because if he's listening to music that is too loud for his of her ears, he won't rest as he should be and, because of fatigue, your child will become more and more violent over time.
