Why quite sad ? There's nothing like crawling a collection of physical records or books and remind "Oh, I remember when I used to listen to this like crazy" and being able to simply put the record in a player and listen it"
That kind of serendipity is just not possible with digital collections, especially when records get deletted from services without notices, or you have to browse deep in a .mp3 collection you afforded not to lose by not backing it up.
It's nice to have those memories, for sure, but my CDs themselves get completely neglected nowadays - between mp3 rips, and streaming services conveniently tying in with my main hifi setup, the CDs just don't see active service any more. And my kids sure aren't interested :-D
I used to love exploring friends' music collections, seeing where tastes overlap. "Everyone has everything via Spotify" completely eliminates this. And I don't see us going back in any substantially wider sense, the genie's out of the bottle. Ah the march of progress, eh...
