Vinyl didn't die entirely because it was the latest development in mass produced analog media for music (tape was impractical and too costly outside of control rooms or rich people living rooms, and cassettes were too inferior), therefore it defined an era. The CD is dying because it's not the latest development in mass produced digital media for music, and it's just being substituted by other means of doing the same thing, so that it's not going to hit the same memories. Panta Rei and history repeats, so one day we might experience a new paradigm shift, for example if we'll record our music -plus the induced feelings of it- on implantable organic neural networks, so that someone will say "hah, those kids and their inferior analog implant... I'll rather go get some old compact discs to feel how it sounded the real thing!".
