Anything and everything that requires a modicum of skill to make or is aurally pleasing to my eardrums. It all depends on the mood I'm in. I've been known to listen to Usher's "More" when I feel like getting pumped about something. I listen to Poets of the Fall when I feel inspired, or emotionally driven. I listen to Tool when I want to enter a surreal mindset. When I'm pissed or angry I listen to tons of different kinds of metal bands.
All depends.
All depends.
