It seems surprisingly difficult to find an iOS Last.fm scrobbler that actually works with AirPlay.

I just want an app that automatically scrobbles my Apple Music plays, even when I'm streaming to my HomePod. Is there any app that can do this reliably?

@hongminhee not sure if it helps, but maybe @ListenBrainz supports that? there's https://github.com/metabrainz/listenbrainz-ios
