I'm trying hard not to judge, but the "Infinite Personal Jukebox" sounds nightmarish to me — and I don't just mean to me, personally, but for humanity as a whole.

You are describing a world in which music is devoid of any social context. No sharing songs with friends, no replaying the first song you danced to with a loved one, no seeing live performances, no researching who inspired your favorite artists — because in this world "inspiration" doesn't exist. Nothing will ever force you to reevaluate a genre you'd written off, or ponder tough questions — in fact, no media will ever challenge or surprise you in any way.

That is a world in which one of our most primal connective threads has been robbed of its social and emotional value. It's just elevator music for our own private elevators.

I'd posit Spotify already is an "infinite personal jukebox" for a lot of people.

We can have both. People will still want that social context, and will go to concerts and so on. But not for every song.
