MusicService
Synchronize playlists to cloud storage as high-quality MP3 files

MusicService is a Dockerized microservice that synchronizes YouTube playlists and other supported providers with cloud storage by downloading videos, converting them to MP3, adding cover art, and uploading via WebDAV. It runs as a container with a simple web UI and can monitor playlists for new tracks automatically.
Key Features
- Downloads audio/video from a wide range of sites using youtube-dl/yt-dlp backends
- Monitors playlists and channels for new items and queues downloads automatically
- Converts video files to high-quality MP3 using ffmpeg and embeds cover art and basic metadata
- Uploads resulting MP3s to any WebDAV-compatible cloud storage (Nextcloud, ownCloud, etc.)
- Tracks already-downloaded songs to avoid duplicates and unnecessary downloads
- Runs as a Docker container with a web UI (default port 5678) and provided Docker Compose setup
Use Cases
- Maintain a personal MP3 music library in Nextcloud by automatically syncing selected YouTube playlists
- Archive and backup favorite mixes or artist uploads to a private cloud drive
- Automate scheduled or continuous ingestion of new tracks for a home media collection
Limitations and Considerations
- Functionality depends on upstream downloader and ffmpeg; changes to provider sites can temporarily break downloads
- Intended for personal/home use; not a scalable enterprise ingestion pipeline
- Requires a WebDAV-capable storage endpoint and a host capable of running Docker containers
MusicService is a focused tool for automating the download, conversion, and storage of online music sources into a managed MP3 collection on WebDAV storage. It is lightweight to deploy via Docker and is useful for home servers and personal media management.
