Here’s an improved version of your question for clarity and consistency:
“I’d like to know if it’s possible to sync ‘likes’ between Plex and Jellyfin. I like Plex’s sonic analysis, but Jellyfin doesn’t have it. I use Jellyfin as a server for Feishin, a Windows client with a Spotify-like interface, where I listen to music and mark songs as ‘likes.’ Is it possible to sync these ‘likes’ with Plex using Synfonium as an intermediary so I don’t have to manage ‘likes’ in both applications separately?”
Is there anything in this question you’d like me to elaborate on?
