And further more, I think, I have the right one here,
to have access to all the "music" packages, 'xmms-mp3' included :

rpmfusion.org
http://rpmfusion.org/Configuration

Please click this line on the site :
' RPM Fusion free for Fedora 8, 9 or 10 '
and
' RPM Fusion nonfree for Fedora 8, 9 or 10 '

to download 2 small packages with repositories,
install them with # rpm -Uvh <package>
and the repositories will be set up automatically in /etc/yum.repos.d

( Or use " Command Line Setup using rpm " )

..... And then try # yum search xmms .

Good luck !
