I get what scop meant. Family vehicles had cassette or 8-track players when I was a kid and I figured out how to use my parents' record player, but for the purposes of what he was getting at, CDs are a more "analog" experience than streaming music, and give you a feel for what playing an album is like. You have to physically put in and remove the disc to change the music, whereas streaming gives you any song at your fingertips.
