The sound you don't remember hearing
Pocket edition. This is a shorter version of a longer article; you can read the full edition when you have more time.
Try something: put on one of C418's piano pieces, without warning, for someone who played Minecraft as a kid. You'll see the face before the memory. And that person, in all likelihood, never once said "I like this server for the music".
What happens there has a name in psychology. Petr Janata studied what are called music-evoked autobiographical memories: a piece doesn't bring back only the piece, it brings back the place, the time of day and who you were being. And it brings back more when you heard it without paying attention, while doing something else. Music you heard in the background a thousand times sticks better than music you listened to on purpose.
That's the oddity of ambient sound. It's the layer that gets decided least and works hardest. The waves, the wind, a few gulls, the distant hum of a place with people in it: nobody joins a server for that, nobody mentions it in a review, and it's one of the first things that takes someone back to an afternoon ten years ago.
That's why the total silence of so many lobbies is a costly mistake. A quiet place isn't read as understated: it's read as empty. And sound isn't there to decorate, but to give the one piece of information sight doesn't fully give: that someone else is there.
In the end, almost nobody remembers a server for what they saw. They remember it for what was playing while they were doing something else.
