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 it's funny you mention this, I actually mentioned Last.FM in one of my answers after my #RubyWorld talk! I've been using it for many years. It seemed to have a heyday about 15 years ago. I still use it across various listening services.
