Same here; I have been listening to streaming stuff less and less...but my reasons are:
1. Between so many work/day-job meetings, seldom in front of a laptop with the opportunity to work with headphones, and music in the background.
2. When I'm mobile - and on my mobile/away from laptop - I'm just too stingy with my mobile data plan. (Maybe its my age, or cuz of family, but priorities of data plans change with growing families ;-)
