Homepage of the project: http://web.ics.purdue.edu/~kuliniew/music-applet/ This software is the replacement of rhythmbox-applet, then I think that bug #63155 can be marked deprecated in favour of this.
Created attachment 85342 [details] music-applet-0.9.1.ebuild
using it for 3 months now, not seen serious bugs. It permits to control different players (3 supported for the moment).
Version bump to 0.9.2, the new ebuild can be found on sunrise overlay[0] [0] http://gentoo-sunrise.org/cgi-bin/trac.cgi/browser/sunrise/gnome-extra/music-applet
added to the portage tree. Thanks
