The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. (It also downloads cover art for albums it imports.) Then it provides a bouquet of tools for manipulating and accessing your music.
Because beets is designed as a library, it can do almost anything you can imagine for your music collection. Via plugins, beets becomes a panacea:
- Embed and extract album art from files’ tags.
- Listen to your library with a music player that speaks the MPD protocol and works with a staggering variety of interfaces.
- Fetch lyrics for all your songs from databases on the Web.
- Manage your MusicBrainz music collection.
- Analyze music files’ metadata from the command line.
- Clean up crufty tags left behind by other, less-awesome tools.
- Browse your music library graphically through a Web browser and play it in any browser that supports HTML5 audio.
If beets doesn’t do what you want yet, writing your own plugin is shockingly simple if you know a little Python.
