The packages for GNOME Music are now in Fedora Rawhide and openSUSE Factory!
Fedora Rawhide (will be included in Fedora 20, by Mathieu Bridon):
openSUSE Factory (will be in openSUSE 12.3 – GNOME:STABLE:3.10 and openSUSE 13.1):
Of course, GNOME Music is still available at our OBS repository for Fedora 19 and openSUSE 12.3 (GNOME:STABLE:3.8): https://build.opensuse.org/package/show/home:arnelborja:gnome-music:git/gnome-music
Thank you Dominique Leuenberger for accepting my package! 😀
