Quod Libet (from the Latin ex falso quodlibet^[1]) is a GTK+-based audio player application written using the Python programming language. Its main design goal is to provide a way for users to organize their music library however they want.

One of Quod Libet's unique features is the ability to search and construct playlists based on search terms or regular expressions. Quod Libet includes a tag editor (also available separately as Ex Falso) which can alter the metadata of groups of files.

Quod Libet uses the GStreamer multimedia framework to handle audio playback. File format support is dependent on which GStreamer decoding modules the user has installed, although MP3 and Ogg are supported by default.

Quod Libet can be extended by writing plugins as Python scripts. Plugins available from the Quod Libet website can, among other things, add advanced editing features, synchronize with MusicBrainz, copy songs to portable digital audio players, and display on-screen song change notifications. Quod Libet also supports last.fm via the QLScrobbler plugin, which sends details on songs played to the last.fm server so that they may be added to a user's music profile. An unofficial patch is available to show Similar Artists, Top 10 Songs and Top 10 Albums, derived from last.fm. Unofficial last.fm patch

Quod Libet's claim to fame may well be its generation of a very strange bug report^[2], and accompanying patch^[3].
