Lidarr is a music collection manager inspired by the Sonarr-style workflow, built for Usenet and BitTorrent users. It monitors artists and releases, then automates downloading and organizing music into a structured library.

Key Features

Monitors artists and release feeds (including RSS) to detect new music
Searches indexers and sends downloads to clients, with support for manual and automatic selection
Scans existing libraries to import music and download missing tracks/albums
Automatically sorts and renames files using configurable naming rules
Upgrades existing files when better quality formats become available
Failed download handling with retries using alternative releases
Integrations with common Usenet download clients and media servers for notifications/library updates

Use Cases

Maintain an always-up-to-date music library with automated downloads and imports
Fill gaps in an existing music collection by scanning for missing items
Standardize music folder and file naming across large libraries

Limitations and Considerations

Metadata and artist-adding features depend on external metadata services; outages can impact library import and artist lookup

Lidarr is a strong choice for users who want automated music acquisition and library management with fine-grained control over quality, naming, and download workflows. It fits well alongside other media automation tools and common download clients in a homelab setup.
