Exaile is a media player aiming to be similar to KDE's AmaroK, but for GTK+. It incorporates many of the features from AmaroK (and other media players) like automatic fetching of album art, handling of large libraries, lyrics fetching, artist/album information via the wikipedia, last.fm support, and optional iPod support (assuming you have python-gpod installed). In addition, it includes a built in shoutcast directory browser, tabbed playlists (so you can have more than one playlist open at a time), blacklisting of tracks (so they don't get scanned into your library), downloading of guitar tablature from fretplay.com, and submitting played tracks on your iPod to last.fm.
