I listen to any kind of music it's really dependant on my mood. I normally listen to stuff like As I Lay Dying, Tool, Still Remains, The Number Twelve Looks Like You, Unearth, Rumplestiltskin Grinder, The Offspring, Ill Nino, and so on.
That is what my computer looks like (thats not my actual computer). As for the specs.
