The worlds are different, certainly. I'm different - once I was young, now I am not so young. Music appreciation, however? No difference, outside of the tools used. When I was a young tadpole I'd get excited about an album after hearing a single on the radio (or parts of the album), then I'd go buy it if I had the funds, play it to death and then years later I'd wax nostalgic about it. Fast forward to today, replace radio with streaming and basically the same process occurs. So what's really changed here?
