Spotify is still scrobbling!

Anyone found a better scrobbling service? Preferably that one can self host?

I believe FunkWhale is attempting something along these lines: https://fediverse.party/en/funkwhale/

https://listenbrainz.org/ is open source (from the MusicBrainz ppl), though not really intended for self-hosting.

You can import your Last.fm history over to ListenBrainz too. Most of the 'scrobbling' apps will work with ListenBrainz also.

I had even managed scrobbling from the iPod classic. There used to be a windows app that would keep track of all the music listened to since <last scrobble> and would scrobble the bulk, in batches.
