Quod Libet is a cross-platform free and open-source music player, tag editor and library organizer. The main design philosophy is that the user knows how they want to organize their music best and is built to be fully customizable and extensible using regular expressions. Quod Libet is a GTK+-based audio player that is written in Python, and uses the Mutagen tagging library. Using the same tools underlying Ex Falso the user can edit any of the tags or metadata in the file.
Quod Libet is also very scalable, able to handle libraries with over 10,000 songs with ease. It contains a full feature set that one would expect from any modern media player, such as multimedia keys, simple tag editing, the ability to rename and organize the music files themselves (rather than simply an internal database of songs), AudioScrobbler to sites such as
Last.fm or Libre.fm, and full Unicode support
Quod Libet is available on a full range of GNU/Linux distributions and has been used on,
FreeBSD, Mac OS X, and Windows as well, requiring only PyGObject, Python, and an OSS or ALSA compatible audio device. The Xfce netinstall disk image provided by the Debian project installs Quod Libet as the default music program.
