From Amarok Wiki
This page lists help and instructions for those using Fedora.
Installing Amarok
Fedora includes PackageKit, so go to (gnome) System -> Add/Remove Software or (kde) System -> Software Management, search for amarok and select it for installation. Alternatively, use yum directly:
yum install amarok
Phonon Backends
Xine and GStreamer are both available as Phonon backends in Fedora. Xine is currently recommended, but you may find GStreamer works better for you.
Xine (recommended)
yum install phonon-backend-xine
GStreamer
yum install phonon-backend-gstreamer
For more on Phonon, see the Phonon page.
MP3 Support
Fedora, by default, does not include MP3 support for legal reasons. To enable MP3 support, the rpmfusion repository should be enabled. Configuration instructions for the rpmfusion repository can be found here.
Once rpmfusion is enabled see the MP3 on Fedora page for installation instructions.
