"...Moreover, I inform you that although I have nothing against you except for how you have hurt me, I profusely reject metal. Why? Because the music is dark, violent, and dull and encourages young people to walk the path of sin and become increasingly enclosed in a melancholy reverie, melodramatic and pointless. I will not lie, I heard metal bands and have rejected them.
To give an example, I will mention Metallica. The singer, Hetfield, is mediocre and shouts excessively, completely lacking the melody with which I was born. And the guitarist only makes noise. Where is the music, then? Another band that I've also heard is Megadeth. I thought it was different, but I was wrong. The singer uses a vocal style that I dislike, like something that makes me feel like crying. And the other musicians in the band... I'd rather not give an opinion."
-Justin Bieber on hard rock/metal genre of music
"I have seen the need to respond to the insults received yesterday from Justin Bieber, since his words have hurt my pride for referring to my art and my music negatively. The truth is, I felt really bad last night when I learned this because with all my years in music, I don't know what to do. I honestly do not know that all my years in this career have been disqualified by inexperienced people moving masses in a way that does not please me.
Technically, I could have taken legal action. But I choose not to, due to the boy's age... I will not torment him with a legal procedure. My sources have informed me that [Dave] Mustaine [from Megadeth], who is in his own right, has decided to take legal action but I doubt he will continue. We know that Dave is temperamental, but he has a good heart and this boy knows not what he says.
I'm not criticizing my colleague for going as low as him, but the only thing I do wanna say is [for Bieber to] have respect, which is what he lacks. He should learn that a momentary and transitory success does not rewrite the history of music. I also want to say that he has a huge future ahead and should use discretion. Not for him to impose the market.[?]
What struck me, of course, is your criticism of my public, to whom I owe everything because they made me who I am. They helped me achieve the transformation from being a nobody to being James Hetfield from Metallica. You cannot classify them as depressed, melodramatic, and dark. By doing that, you are trying to say that our style of music influences them to feel hatred. In the end, you're completely disqualifying our [musical] style."
