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...
@Gargron 100%! It is the service I’ve used for the longest time in my life. I had a last.fm account since 2005, before any of the current “social media” existed.
