graphical jukebox for large music collections

 gmusicbrowser is a powerful graphical browser which supports libraries
 with a very large number of songs (over 10,000).
 .
 It can use multiple inputs and has native support for MP3, Ogg, and
 FLAC files. It also supports mass-renaming and mass-retagging of a song
 library, multiple genres per song, ratings, and customizable labels.
 .
 gmusicbrowser has a customizable window layout, and comes with plugins
 to use Last.fm, retrieve lyrics, or find album pictures and WebContext
 (using the Mozilla or WebKit engines to display the artist's page on
 Wikipedia and search for lyrics with Google).
