Quod Libet

Overview

Quod Libet is a free desktop music player built around a searchable, editable music library. It is best suited to listeners who care about precise tagging and advanced ways to find music. Its extensive library tools are a strong case for it, provided you are comfortable with a playback dependency and, on macOS, an unofficial current image.

Key features

Quod Libet uses GTK+, Python and the Mutagen tagging library, and is designed to handle collections with tens of thousands of songs. Browsing by tag or directory works alongside searches using ordinary text, regular expressions, structured Boolean logic or Python expressions. That range gives collection-focused listeners room to find tracks by detailed criteria; users who only need a basic play button may find little reason to use the more involved search modes.

Tag editing supports Unicode, batch changes and file renaming based on tags. These are useful tools for maintaining a large, inconsistently organized collection, not just viewing metadata. Playback features include Replay Gain, shuffle, album art and a configurable play queue. Playlists can be imported and exported in XSPF, M3U and PLS formats.

Supported formats include MP3, Ogg Vorbis, Speex, Opus, FLAC, Musepack, MOD, XM, IT, WavPack, MPEG-4 AAC, WMA, MIDI and Monkey’s Audio. Playback requires GStreamer or xine-lib; additional GStreamer plugins provide support for some formats and outputs. That dependency is worth accounting for before choosing Quod Libet, especially if you expect every format or output to work without configuration.

The player includes podcast browsing, which checks feeds every two hours and allows episode downloads, as well as Internet radio. Radio supports MP3 and Ogg Vorbis streams; other formats may need suitable GStreamer plugins, and stations cannot be added to playlists or the play queue. Quod Libet also supports SoundCloud browsing and streaming with login and native favorites. Its Python plugin system has more than 80 contributed plugins, including integrations for MusicBrainz, CDDB, Last.fm, Sonos, Logitech Squeezebox, dBus and MQTT. Ex Falso shares Quod Libet’s tag-editing backend but is a separate option for editing tags without an audio player.

Pricing

Quod Libet costs nothing. It is free software under GNU GPL version 2 or later, though alternate licensing terms may apply to some files or modules. There is no paid tier to unlock, so listeners get the same no-cost option whether they want basic playback or the broader library and tagging tools.

Platforms

Downloads are provided for Linux, Windows and macOS. The Quod Libet 4.6.1 macOS disk image is marked unofficial, which makes the macOS option less straightforward than the Linux and Windows downloads. The project says files are signed with its key and provides SHA256 and PGP verification links for release tarballs and many installers.

Who it's for

Choose Quod Libet if you keep a substantial music collection and want control over how it is searched, tagged and played. Its batch editing and expressive search make it a better fit for deliberate library management than for listeners seeking a minimal player. If you want tag editing but intend to keep another player, Ex Falso is the more focused companion.

Pros and cons

• Pro: Detailed tag, directory and expression-based search makes large collections easier to organize and query.
• Pro: Unicode and batch tag editing, plus file renaming based on tags, support ongoing library cleanup.
• Pro: Broad format support, playlist exchange, podcasts, SoundCloud and a large plugin collection give the free player considerable flexibility.
• Con: Playback depends on GStreamer or xine-lib, and some format and output support requires additional GStreamer plugins.
• Con: Internet radio stations cannot be saved in playlists or the play queue, limiting how well radio fits into a music-listening workflow.
• Con: The 4.6.1 macOS image is unofficial, so macOS users have a less reassuring current download option.

Alternatives

Audio Player Software and Media Player Software are broader starting points for comparing category options.

• foobar2000 is another free audio player, with versions for Android, iOS, Linux, macOS and Windows; consider it if mobile support matters.
• Music Player Daemon is free software for Linux, macOS, Windows, Android, API and self-hosted environments; choose it if that platform range better matches your setup.
• Winamp for Artists has a free plan and a €12.99 a month Ultra plan billed annually; consider it if an artist-focused service fits better than a desktop library player.
• AIMP is free for Android, Linux and Windows, making it an option if you do not need macOS support.
• Audacious is a free open-source audio player for Linux, macOS and Windows; consider it as another no-cost desktop option.
• BBC Sounds is free on Android, iOS and the web, but is available exclusively to UK listeners.
• Audirvāna is a paid player with a free trial and a Studio Classic plan at $7.99 a month; choose it if you prefer a paid option with integrated streaming content.
• JRiver Media Center is a paid player for Linux, macOS and Windows with a free trial; consider it if a paid alternative better suits your needs.

Verdict

Quod Libet is a strong choice for desktop listeners who want a free player that can handle a large collection and give them unusually precise control over tags and search. Its library tools are the main reason to choose it. Look elsewhere if you need radio stations in your queue or playlists, want playback without managing GStreamer or xine-lib, or would rather avoid the unofficial macOS 4.6.1 image.
