A few weeks after Amarok 2.8
was released on the KDE side, GNOME's Rhythmbox 3.0 music player is now available.
Rhythmbox 3.0 made it out this week for the GNOME 3.9.91 Beta and with the 3.0 release its plug-ins now use Python 3 rather than Python 2. Additionally, there's a new task progress bar, support for composer tags, restyling to icons and other user-interface elements, better introspection of everything, playlist settings in a XML file, and various other fixes. There's also a long list of bug-fixes.
If you use Rhythmbox as your GTK+ music player, Rhythmbox 3.0 looks like it's worth checking out. More details can be found on the Rhythmbox mailing list
