Aaaah, my heavy brother!
I'm pretty big heavy metal fan, SOAD, (Disturbed too) Nightwish, Sonata Arctica, In Flames, Guns N' Roses, DragonForce, Bullet For My Valentine, Breaking Benjamin, Avenged Sevenfold, Trivium, Metallica, and many many others. I'm just interested in some good songs, however still my number one is Metallica.
