Do you listen to music in the car? in public? How many hours a day do you have music playing?
as for me, I listen to music when I drive, just a local "alternative to the alternative" station which plays local and popular punk, rock, metal, and all the underground subgenres :D
at home I might listen to my pandora station for an hour or two every few days.
I'd say I spend 3-8 hrs a week listening to music.
