Why do you listen to metal?

I recently started to listen to Heavy Metal and I have to say I really like it.What I like to this music is that it is instrument based and it gives a vibe that fullfills you with energy.I started to listen with a combination of clasic and black metal bands(Like Metallica,Maiden,Slayer and Gorgoroth,Mayhem,Bathory).So I was wondering :Why do you REALLY listen to metal and what bands and genres you listen to mostly?
