It's not really ready for prime-time yet, so I haven't submitted a review request for Fedora, but if you want to give it a try, I've pushed it to a side-repo.
If you're running Rawhide, give it a try:
# curl http://repos.fedorapeople.org/repos/bochecha/gnome-music/fedora-gnome-music.repo > /etc/yum.repos.d/fedora-gnome-music.repo # yum install gnome-music
Note: It relies on a yet unreleased version of grilo, so that will come in as a dependency and replace the version provided by Fedora.
I'll try to keep it relatively up-to-date with upstream development, until there's a release to send into Fedora.
