What I miss more than anything is friends playing me their latest favourite album when I visit them.
This is probably at least partly because you got older. That is very much a youth phenomenon, and maybe for some hardcore music fans.
And today you don't have to wait until you go over to them. They send you a Spotify link, and you check it out at home.
More & more, people are just treating music like it's the radio rather than albums that they want to listen to closely over & over in order to hear more detail, depth & feeling in it
I'm not sure people ever wanted that. Back in the dark ages before streaming, you had no choice. You could afford maybe one album per month if you were really into music, and casual listeners bought even fewer albums. You had to listen over and over to the same few records. And since you could not prepare playlists you had to manually skip the crappy songs on the album, so you were forced to know them too.
