I think the closest thing I'm aware of is last.fm.

Based on some light surfing, it appears there are two less commercial alternatives: ListenBrainz and libre.fm (the hosted version of GNU FM). An interested reader could peruse https://github.com/topics/scrobbler to find even more projects

- https://listenbrainz.readthedocs.io/en/latest/index.html

- https://libre.fm/popular-page.php and https://github.com/foocorp/gnu-fm which is shown as archived. Related to that, while digging into libre.fm I found https://github.com/foocorp/hacienda#why-now which claims that last.fm federates, but I wasn't able to find any further references to that
