## What it is
Lidarr is a self-hosted music collection manager for Usenet and BitTorrent users, modeled after Sonarr. It monitors RSS feeds for new releases from favorite artists, grabs, sorts, and renames them via download clients, and can automatically upgrade library quality.

## Use cases
- automatically download new albums from artists I follow
- manage my music library and fill in missing tracks
- automatically upgrade music files to better quality when available
- rename and tag my music collection consistently
- integrate music downloads with SABnzbd, NZBGet, Plex, and Kodi
- self-hosted alternative for automated music downloading via usenet and torrents

## When to choose
- you want automated, hands-off music downloading and library management
- you already use Sonarr/Radarr and want the same workflow for music
- you need Usenet and torrent indexer/download client integration with quality profiles
- you want metadata tagging and renaming for a large music library

## When to avoid
- you only need a simple music player rather than a downloader/manager
- you want streaming or music discovery rather than file collection
- you cannot run a self-hosted server or Docker container
- you need a solution that does not depend on external indexers and metadata services

## Facets
- artifact type: application
- maturity: active
- function: workflow-automation, http-server, search-engine
