Yeah, I was about to respond with something like this. I knew that CDs came out in the early 80's, but I still more or less associate them with the 90's; it wasn't expected that you bought a CD for music until then. As a very little kid I had cassettes for my sing-along tunes, by the time 6 or 7 (1997-1998), it feels like pretty much everyone had made the jump to CDs.
