Ever since I was 12 years old I had to defend my love for heavy metal against those who say it's a less valid form of music. My answer now is that you either feel it or you don't. If metal doesn't give that overwhelming surge of power that make the hair stand up at the back of your neck, you might never get it, and you know what? That's okay, because judging by the 40,000 metalheads around me we're doing just fine without you.
