Why do we listen metal??

I was just surfing the net. I found a topic in keepmetalalive group of hi5 that Why do we listen metal?? started by Goray Kta(nickname) This question made me think for a while. I just keep on thinking about the topic but can't find a particular answer. There is just a simple answer in my mind that, I listen to metal cause i like it. Is that the reason what the metal heads say. Definitely Not. I really like the thoughts of Cryptoxic(nickname)
He like metal because

"I love metal, 'cause it provides freedom to the ultimate extent, you don't have to follow any trends, or anything. It has got power in making us do anything. I listen to Dark Tranquillity when in loneliness, and it is so 'soulful' that... you know!
Metal has always rejected trends, policies, viewpoints, etc. that many follow-up sheeps embrace, well I don't want to involve in their shitty business."

I pretty like his thoughts but still wandering why i listen metal?? I really can't the particular answer till now.

Guys.. Why do we listen metal??????
