Overview Lidarr is a free and open-source media management tool that can automatically download, organize and manage your music collection.  Organize your existing collection, add new artists from MusicBrainz or import lists to keep up-to-date.  Always be sure that your media has the correct metadata for your Plex or Jellyfin media server. Connects to Prowlarr to aggregate Usenet and Torrent queries to multiple sources into one unified search result. View all of your upcoming albums on a calendar and export it for your calendar app. Perform automatic searches to find media within your specifications, or manually search through the results. Blacklist any failed downloads and Lidarr will search for a different download. Add a single album to your library, or make sure you have every album from that artist.
