I'm a bit sad that last.fm isn't more popular. To preempt, yes, it's still a centralized commercial company, but at least it's agnostic about where you listen to music. Instead, most people have their listening habits locked within specific streaming platforms like Spotify or YouTube Music, and rely on them to make that information available to them once a year...
I've been using last.fm since 2008 and the only device in my possession that isn't scrobbling is the record player. It is a bit amusing that for how privacy-conscious I am in all other ways I'm happy to share what I listen to, when, and how much. But that's the thing, it's my choice.
@Gargron I think music listening is one of those inherently social (and also personal) activities. It's a good fit for a social web update actually!
