I'm surprised a thread like this hasn't been created yet. (To my knowledge)
I'm sure everyone here is wondering what kind of music the people here on Game-Hackers listen to, I'll start.
I personally like rock, metal, techno. I dislike everything from hip-hop to rap, soul, county, etc.
My favorite bands are Metallica, Iron Maiden, Black Sabbath, Linkin Park, Breaking Benjamin, All That Remains.
Those are just a couple.
