I am slowly migrating away from Last.fm (which still has one blogging friend who randomly quotes my statistics) to ListenBrainz. Initial import from Last.fm works just well - and after that, I needed to improvise:
- Music player: cmus.
- Scrobbling: cmus-status-scrobbler with both services enabled in the configuration file.
My “status display program” is a small shell script that does not (much) more than call cmus_status_scrobbler.py. Works just well: ListenBrainz, Last.fm. :-)
strawberry music player (desktop) and pano scrobbler (android) also do parallel scrobbling; they are my mechanism
Strawberry does not have macOS developers right now, and I also use iOS. But yes, on some systems, actively maintained alternatives exist.
