I listen to all music except heavy metal music
Why don't you listen to heavy metal? It has been around since the 1960's.
I know but it is not healthy to listen to such music
I can see your point, metal music is sometimes performed with aggression and machismo 
Did you know where the music originated from?
It was largely developed in the United Kingdom where it is still wildly popular today
I see. I will rather listen to Rap music rather than heavy metal
Well heavy metal does get its roots from blues rock the same way hip hop got its roots from blues
