+      Quod Libet is a GTK+-based audio player written in Python, using
+      the Mutagen tagging library. It's designed around the idea that
+      you know how to organize your music better than we do. It lets
+      you make playlists based on regular expressions (don't worry,
+      regular searches work too). It lets you display and edit any
+      tags you want in the file. And it lets you do this for all the
+      file formats it supports. Quod Libet easily scales to libraries
+      of thousands (or even tens of thousands) of songs. It also
+      supports most of the features you expect from a modern media
+      player, like Unicode support, tag editing, Replay Gain, podcasts
+      & internet radio, and all major audio formats.
