Tame Your Music Collection with Beets
If you've ever spent more time organizing your music files than actually listening to them, you're not alone. For developers and music enthusiasts with large digital libraries, metadata is a constant battle—misspelled artist names, inconsistent album titles, and missing genres. Manually fixing this is a tedious, never-ending chore.
Enter beets, the music library manager and MusicBrainz tagger that does the heavy lifting for you. It's a command-line tool written in Python that automatically fixes your music's metadata, organizes your files into a consistent directory structure, and even helps you discover new music. It's like having a meticulous, music-obsessed librarian automate your entire collection.
What It Does
Beets scans your directories of music files, compares them against the MusicBrainz database, and automatically corrects tags—things like artist, album, year, and track number. Once your files are tagged correctly, it can then rename and move them into a clean, predictable folder structure you define (e.g., Music/Artist/Album/Track Number - Title.mp3). It goes beyond simple tagging; it can also fetch album art, convert audio formats on import, and identify duplicate tracks.
Why It's Cool
The magic of beets is in its flexibility and its plugin ecosystem. The core tagging is powerful on its own, but its real power is unlocked through its extensive plugins. You can extend beets to:
- Fetch lyrics and store them directly in your audio files.
- Create a web-based player to stream your collection from anywhere.
- Sync your library with any device using its built-in sync command.
- Integrate with last.fm to scrobble your plays and get recommendations.
It's built by and for developers who like to script things. You can configure every aspect through a simple YAML config file, and its command-line interface is straightforward and powerful. It respects your data and gives you a preview of changes before it makes them, so you're always in control.
How to Try It
Beets is a Python package, so you can install it easily with pip. It requires Python 3.6 or later.
pip install beets
Once installed, you'll want to configure it. The quickest way to get started is to run beet config to generate a default config file (~/.config/beets/config.yaml), which you can then edit to point to your music directory and set your preferred file structure.
To import your first batch of music, navigate to a folder containing some albums and run:
beet import /path/to/your/music/
It will walk you through the process, suggesting matches and asking for confirmation. After that, your library will be clean, consistent, and effortlessly organized.
Final Thoughts
Beets is one of those niche but incredibly valuable tools that solves a specific problem perfectly. It's not flashy, but it's incredibly effective. If you have a messy music library that you've been meaning to fix "someday," beets is the automated solution that finally makes it happen. It turns a weekend-long manual tagging project into an afternoon of automated curation. For developers, it's a great example of a practical, well-built CLI tool that just gets out of your way and does its job brilliantly.
