beets 1.3.2

This update brings new plugins for fetching acoustic metrics and listening statistics, many more options for the duplicate detection plugin, and flexible options for fetching multiple genres.

The "core" of beets gained a new built-in command: beet write updates the metadata tags for files, bringing them back into sync with your database. Thanks to Heinz Wiesinger.

We added some plugins and overhauled some existing ones:

• The new echonest plugin can fetch a wide range of acoustic attributes from The Echo Nest, including the "speechiness" and "liveness" of each track. The new plugin supersedes an older version (echonest_tempo) that only fetched the BPM field. Thanks to Pedro Silva and Peter Schnebel.
• The duplicates plugin got a number of new features, thanks to Pedro Silva:
  • The keys option lets you specify the fields used detect duplicates.
  • You can now use checksumming (via an external command) to find duplicates instead of metadata via the checksum option.
  • The plugin can perform actions on the duplicates it find. The new copy, move, delete, delete_file, and tag options perform those actions.
• The new mpdstats plugin collects statistics about your listening habits from MPD. Thanks to Peter Schnebel and Johann Klähn.
• lastgenre: The new multiple option has been replaced with the count option, which lets you limit the number of genres added to your music. (No more thousand-character genre fields!) Also, the min_weight field filters out nonsense tags to make your genres more relevant. Thanks to Peter Schnebel and rashley60.
• lyrics: A new --force option optionally re-downloads lyrics even when files already have them. Thanks to Bitdemon.

As usual, there are also innumerable little fixes and improvements:

• When writing ID3 tags for ReplayGain normalization, tags are written with both upper-case and lower-case TXXX frame descriptions. Previous versions of beets used only the upper-case style, which seems to be more standard, but some players (namely, Quod Libet and foobar2000) seem to only use lower-case names.
• missing: Avoid a possible error when an album's tracktotal field is missing.
• ftintitle: Fix an error when the sort artist is missing.
• echonest_tempo: The plugin should now match songs more reliably (i.e., fewer "no tempo found" messages). Thanks to Peter Schnebel.
• convert: Fix an "Item has no library" error when using the auto config option.
• convert: Fix an issue where files of the wrong format would have their transcoding skipped (and files with the right format would be needlessly transcoded). Thanks to Jakob Schnitzer.
• Fix an issue that caused the id3v23 option to work only occasionally.
• Also fix using id3v23 in conjunction with the scrub and embedart plugins. Thanks to Chris Cogburn.
• ihate: Fix an error when importing singletons. Thanks to Mathijs de Bruin.
• The clutter option can now be a whitespace-separated list in addition to a YAML list.
• Values for the replace option can now be empty (i.e., null is equivalent to the empty string).
• lastgenre: Fix a conflict between canonicalization and multiple genres.
• When a match has a year but not a month or day, the autotagger now "zeros out" the month and day fields after applying the year.
• For plugin developers: added an optparse callback utility function for performing actions based on arguments. Thanks to Pedro Silva.
• scrub: Fix scrubbing of MPEG-4 files. Thanks to Yevgeny Bezman.

beets 1.3.1

This release boasts a host of new little features, many of them contributed by beets' amazing and prolific community. It adds support for Opus files, transcoding to any format, and two new plugins: one that guesses metadata for "blank" files based on their filenames and one that moves featured artists into the title field.

Here's the new stuff:

• Add Opus audio support. Thanks to Rowan Lewis.
• convert: You can now transcode files to any audio format, rather than just MP3. Thanks again to Rowan Lewis.
• The new fromfilename plugin guesses tags from the filenames during import when metadata tags themselves are missing. Thanks to Jan-Erik Dahlin.
• The ftintitle, by @Verrus, is now distributed with beets. It helps you rewrite tags to move "featured" artists from the artist field to the title field.
• The MusicBrainz data source now uses track artists over recording artists. This leads to better metadata when tagging classical music. Thanks to Henrique Ferreiro.
• lastgenre: You can now get multiple genres per album or track using the multiple config option. Thanks to rashley60 on GitHub.
• A new id3v23 config option makes beets write MP3 files' tags using the older ID3v2.3 metadata standard. Use this if you want your tags to be visible to Windows and some older players.

And some fixes:

• fetchart: Better error message when the image file has an unrecognized type.
• mbcollection: Detect, log, and skip invalid MusicBrainz IDs (instead of failing with an API error).
• info: Fail gracefully when used erroneously with a directory.
• echonest_tempo: Fix an issue where the plugin could use the tempo from the wrong song when the API did not contain the requested song.
• Fix a crash when a file's metadata included a very large number (one wider than 64 bits). These huge numbers are now replaced with zeroes in the database.
• When a track on a MusicBrainz release has a different length from the underlying recording's length, the track length is now used instead.
• With per_disc_numbering enabled, the tracktotal field is now set correctly (i.e., to the number of tracks on the disc).
• scrub: The scrub command now restores album art in addition to other (database-backed) tags.
• mpdupdate: Domain sockets can now begin with a tilde (which is correctly expanded to $HOME) as well as a slash. Thanks to Johann Klähn.
• lastgenre: Fix a regression that could cause new genres found during import not to be persisted.
• Fixed a crash when imported album art was also marked as "clutter" where the art would be deleted before it could be moved into place. This led to a "image.jpg not found during copy" error. Now clutter is removed (and directories pruned) much later in the process, after the import_task_files hook.
• missing: Fix an error when printing missing track names. Thanks to Pedro Silva.
• Fix an occasional KeyError in the update-cmd command introduced in 1.3.0.
• scrub: Avoid preserving certain non-standard ID3 tags such as NCON.

beets 1.3.0

Albums and items now have flexible attributes. This means that, when you want to store information about your music in the beets database, you're no longer constrained to the set of fields it supports out of the box (title, artist, track, etc.). Instead, you can use any field name you can think of and treat it just like the built-in fields.

For example, you can use the modify command to set a new field on a track:

$ beet modify mood=sexy artist:miguel

and then query your music based on that field:

$ beet ls mood:sunny

or use templates to see the value of the field:

$ beet ls -f '$title: $mood'

While this feature is nifty when used directly with the usual command-line suspects, it's especially useful for plugin authors and for future beets features. Stay tuned for great things built on this flexible attribute infrastructure.

One side effect of this change: queries that include unknown fields will now match nothing instead of everything. So if you type beet ls fieldThatDoesNotExist:foo, beets will now return no results, whereas previous versions would spit out a warning and then list your entire library.

There's more detail than you could ever need on the beets blog.

beets 1.2.2

This is a bugfix release. We're in the midst of preparing for a large change in beets 1.3, so 1.2.2 resolves some issues that came up over the last few weeks. Stay tuned!

The improvements in this release are:

• A new plugin event, item_moved, is sent when files are moved on disk. Thanks to dsedivec.
• lyrics: More improvements to the Google backend by Fabrice Laporte.
• bpd: Fix for a crash when searching, thanks to Simon Chopin.
• Regular expression queries (and other query types) over paths now work. (Previously, special query types were ignored for the path field.)
• fetchart: Look for images in the Cover Art Archive for the release group in addition to the specific release. Thanks to Filipe Fortes.
• Fix a race in the importer that could cause files to be deleted before they were imported. This happened when importing one album, importing a duplicate album, and then asking for the first album to be replaced with the second. The situation could only arise when importing music from the library directory and when the two albums are imported close in time.

beets 1.2.1

This release introduces a major internal change in the way that similarity scores are handled. It means that the importer interface can now show you exactly why a match is assigned its score and that the autotagger gained a few new options that let you customize how matches are prioritized and recommended.

The refactoring work is due to the continued efforts of Tai Lee. The changes you'll notice while using the autotagger are:

• The top 3 distance penalties are now displayed on the release listing, and all album and track penalties are now displayed on the track changes list. This should make it clear exactly which metadata is contributing to a low similarity score.
• When displaying differences, the colorization has been made more consistent and helpful: red for an actual difference, yellow to indicate that a distance penalty is being applied, and light gray for no penalty (e.g., case changes) or disambiguation data.

There are also three new (or overhauled) configuration options that let you customize the way that matches are selected:

• The ignored setting lets you instruct the importer not to show you matches that have a certain penalty applied.
• The preferred collection of settings specifies a sorted list of preferred countries and media types, or prioritizes releases closest to the original year for an album.
• The max_rec settings can now be used for any distance penalty component. The recommendation will be downgraded if a non-zero penalty is being applied to the specified field.

And some little enhancements and bug fixes:

• Multi-disc directory names can now contain "disk" (in addition to "disc"). Thanks to John Hawthorn.
• web: Item and album counts are now exposed through the API for use with the Tomahawk resolver. Thanks to Uwe L. Korn.
• Python 2.6 compatibility for the beatport plugin, missing, and duplicates. Thanks to Wesley Bitter and Pedro Silva.
• Don't move the config file during a null migration. Thanks to Theofilos Intzoglou.
• Fix an occasional crash in the beatport when a length field was missing from the API response. Thanks to Timothy Appnel.
• scrub: Handle and log I/O errors.
• lyrics: The Google backend should now turn up more results. Thanks to Fabrice Laporte.
• random: Fix compatibility with Python 2.6. Thanks to Matthias Drochner.
