Start with the two packages listed already, xmms and xmms-mp3 and download both of them from;
http://dag.wieers.com/rpm/packages/xmms/
Get the xmms-skins package also so you can choose different skins (the way it looks on screen).
The xmms.spec shows that you also need;
Requires: gtk+ >= 1:1.2.2, unzip
# the desktop file and redhat-menus are redundant requires really
Requires: /usr/share/desktop-menu-patches/redhat-audio-player.desktop
%{!?_without_freedesktop:Requires: desktop-file-utils}
Requires: redhat-menus >= 0.11
So a quick check would be: rpm -qa redhat-menus unzip 'gtk+*' desktop-file-utils
