https://actions.work/listening-post - Listening Post is my macOS multi-scrobbler that works with Last.fm, ListenBrainz, Rocksky, Maloja, Shortcuts, social posting, etc., independent from Spotify or Apple Music. The app can also scrobble shazams (music recognitions) from iPhone and Apple Watch, without the need for an extra app.

Basically, I built the scrobbler of my dreams. I love it to bits! I'm a professional software engineer for ~27 years by now but I only now got around to building that thing. :)
