My dad told me a story about how, when he was a kid, my grandpa flew to Jamaica for a conference and came back with a bunch of calypso CDs.
The thought behind hearing a sound, liking it, identifying it, buying it, and then bringing it back home for your collection is an aspect of music that I think was really special.
I love how accessible music is now, but as the technology gets better and better, I worry that people are choosing less and less what they are listening to.
