I used to spend a lot more time with music as a kid. Now its mostly when I'm working, working out or on the move..
When I'm working, I play my music on my laptop, plug in my Bose headphones, and listen through iTunes
When I go running, I listen to music on my iPod.
When I'm in transit, I listen to it on my WP.
I don't remember when was the last time I turned on the radio.
I do like buying CDs but I don't buy CDs of every artist. Just the ones I'm obsessed with.
Otherwise, its mostly digital music since the iPod revolution.
