Fedora 10 ships with Amarok 1.94. If you install the the amarok-extras-free world package then you may not get your Mp3s to still play. This is because the amarok-extras-free depends on two more packages (dont confuse with dependencies) named: libtunepimp-extras-nonfree and xine-lib-extras-nonfree.
So, to install them run the following command at your terminal:
[email protected] ~]$ sudo yum -y install libtunepimp-extras-nonfree xine-lib-extras-nonfree
