Another alternative is listenbrainz [0], which is also self-hostable [1]. A smaller, lightweight, single user selfhostable alternative, and more about just the stats is Koito [2], and finally because obviously you want to scrobble everywhere at once, you can self-host Multi Scrobbler to scrobble to and from multiple sources at once. Yes, I like scrobbling ;)
Lol, I had no idea scrobbling was popular again. I'm the maintainer of a scrobbler daemon for linux that gets the track info through MPRIS and can send it to last.fm, listenbrainz and libre.fm. :)
