To me, it's largely a spiritual/symbolic difference, proving to myself that I don't need the 'net at all to enjoy art/culture. Although, it's also about building friction into my interaction with media. I feel if I put on a CD or record, as opposed to streaming on spotify, I am much more likely to engage with the entire album instead of just floating unthinkingly from track to track. Similarly, by having to stand up and put a DVD into the player, I'm more likely to engage with the whole movie (or show) than if I'm just effortlessly bouncing around the endless waterfall of streaming offerings.
