It really depends on the mood. I prefer classical, new age or piano music. But sometimes I might listen doom metal if I'm in the mood for it, or when I feel like partying I play some progressive electro, but like I said, classical and new age are my favorites.
Actually that is depend on the situations. When I am in the gym then I like POP music when I am in home or I am in sad then I listen sad songs...
I like it all. all depends on my mood. I get laughed at for jammin out to some good ol country, then later follow up with some hardcore/punk... strange I know..
