Headphones I think it’s called? But lidarr has the best integration given it’s a fork.
If this is about the lidarr metadata being fucked you can try something like https://github.com/blampe/hearring-aid, which has its own issues but is working.
All of the arr stack developers flip their shit if you so much as suggest adding support for a custom metadata server. It is by far the biggest weakness of the stack and it is mind boggling that all the major forks have inherited this behavior from sonarr.
Lidarr shows how foolish this approach is, musicbrainz makes one change and the app is fucked for over three months now with no end in sight. Thetvdb could do this to sonarr, themoviedb could do this to radarr. Adding a method to add other database sites with api access (or even just local data) should be a priority, but they not only dislike the idea, they get mad about it. Oh well, free project, fork it if youre so great, etc etc
