Well, the RealPlayer11GOLD.rpm is actually usable for mp3.

1) su
2) yum --nogpgcheck localinstall RealPlayer11GOLD.rpm
3) exit
.. and play mp3.
There are of course other music players, most with a lot
of dependencies. The RealPlayer11GOLD.rpm depends on
system files, probably already installed.
( libstdc++-4.1.2-44.el5 → libstdc++.so.6 etc. etc.)
And the codecs are included, I could start the 'realplay'
by clicking on an mp3 sample. ( CentOS 5.x / EL5 ).
