Lidarr manages the automated acquisition of discographies and musical artist libraries. It operates on the Acquisition Server (VM-A) and listens on TCP Port 8686.

Following installation, navigate to Settings → General to retrieve your API key for Prowlarr and Overseerr integration.

Navigate to Settings → Media Management and enforce the hardlink rules. Point your Root Folder to the designated audio directory on the storage fabric: `/mnt/data/media/music/`.

Unlike TV and Movies, audio libraries rely heavily on embedded ID3 tags rather than just filenames to structure their databases.

Navigate to Settings → Media Management → Track Naming:

1. Enforce the standard structure: `{Artist Name}/{Album Title} ({Release Year})/{track:02} - {Track Title}`
2. Check the box to Rename Tracks. This ensures wildly formatted torrent downloads are sanitized into a clean, uniform library before Plex ingests them.

Navigate to Settings → Profiles:

1. Rename the primary profile to Lossless FLAC.
2. Edit the profile to explicitly disable all lossy formats (MP3, AAC) unless a FLAC version is entirely unavailable.
3. Set the priority order: `FLAC` > `MP3 320kbps`.

Navigate to Settings → Download Clients:

1. Add qBittorrent.
2. Host: `localhost`
3. Port: `8023`
4. Category: `music-lidarr`

Next Step: Deploy the background self-healing scripts in Cleanuparr & ByParr Maintenance Engines.
