mp3 fc4

[D. Eric Chadbourne]

Hi.  I'm back from over a year in windows land (because of work) and 
just installed fc4 and thought I'd listen to some tunes while getting 
everything set up correctly and of course get stuck on the very first 
problem.

yum install gstreamer-plugins-mp3
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
Parsing package install arguments
No Match for argument: gstreamer-plugins-mp3
Nothing to do


What?  I thought fedora extras were available automagically in fc4?  Do 
I have to add another repository?  What are the cool kids doing now? 
Thanks for any tips.
