So you have beets up and running and you’ve started importing your music. There’s a lot more that beets can do now that it has cataloged your collection. Here’s a few features to get you started.
Fetch album art, genres, and lyrics¶
If you want beets to get any of this data automatically during the import process, just enable any of the three relevant plugins (see Plugins). For example, put this line in your config file to enable all three:
plugins: fetchart lyrics lastgenre
Each plugin also has a command you can run to fetch data manually. For
example, if you want to get lyrics for all the Beatles tracks in your
collection, just type
beet lyrics beatles after enabling the plugin.

Customize your file and folder names¶
Beets uses an extremely flexible template system to name the folders and files
that organize your music in your filesystem. Take a look at
Path Format Configuration for the basics: use fields like
$title to build up a naming scheme. But if you need more flexibility,
there are two features you need to know about:
- Template functions are simple expressions you
can use in your path formats to add logic to your names. For example, you
can get an artist’s first initial using
- If you need more flexibility, the Inline Plugin lets you write
snippets of Python code that generate parts of your filenames. The
equivalent code for getting an artist initial with the inline plugin looks
If you already have music in your library and want to update their names according to a new scheme, just run the move command to rename everything.
Stream your music to another computer¶
Sometimes it can be really convenient to store your music on one machine and play it on another. For example, I like to keep my music on a server at home but play it at work (without copying my whole library locally). The Web Plugin makes streaming your music easy—it’s sort of like having your own personal Spotify.
First, enable the
web plugin (see Plugins). Run the server by
beet web and head to http://localhost:8337 in a browser. You can
browse your collection with queries and, if your browser supports it, play
music using HTML5 audio.
Transcode music files for media players¶
Do you ever find yourself transcoding high-quality rips to a lower-bitrate, lossy format for your phone or music player? Beets can help with that.
convert: dest: ~/converted_music
Then, use the command
beet convert QUERY to transcode everything matching
the query and drop the resulting files in that directory, named according to
your path formats. For example,
beet convert long winters will move over
everything by the Long Winters for listening on the go.
The plugin has many more dials you can fiddle with to get your conversions how you like them. Check out its documentation.
Store any data you like¶
The beets database keeps track of a long list of built-in fields, but you’re not limited to just that list. Say, for example,
that you like to categorize your music by the setting where it should be
played. You can invent a new
context attribute to store this. Set the field
using the modify command:
beet modify context=party artist:'beastie boys'
By default beets will show you the changes that are about to be applied and ask if you really want to apply them to all, some or none of the items or albums. You can type y for “yes”, n for “no”, or s for “select”. If you choose the latter, the command will prompt you for each individual matching item or album.
Then query your music just as you would with any other field:
beet ls context:mope
You can even use these fields in your filenames (see Path Format Configuration).
And, unlike built-in fields, such fields can be removed:
beet modify context! artist:'beastie boys'

Choose a path style manually for some music¶
Sometimes, you need to categorize some songs differently in your file system. For example, you might want to group together all the music you don’t really like but keep around to play for friends and family. This is, of course, impossible to determine automatically using metadata from MusicBrainz.
Instead, use a flexible attribute (see above) to store a flag on the music you want to categorize, like so:
beet modify bad=1 christmas
Then, you can query on this field in your path formats to sort this music differently. Put something like this in your configuration file:
paths: bad:1: Bad/$artist/$title
Used together, flexible attributes and path format conditions let you sort your music by any criteria you can imagine.
