Link plex to your last.fm account so it scrobbles and then let LZ auto-import every 30 min from last.fm. Thats the simplest way.

Koito is fantastic. I’m so ready to dump Maloja but won’t yet until Koito gets an official stable build. Multi-scrobbler is a lifesaver.

Looks interesting but explicitly says it’s “alpha software “ and hasn’t been updated in five years. I’d be weary of using something like this in such a critical situation.
