[CentOS] digikam and mp3 sound on RHEL

Hi All;

after years of running free Linux distros I've finally come to a place where I 
must have solid stability for my work laptop so I've purchased RHEL 
Workstation.

I like it well enough - however I'd like to install digikam and get my system 
to play mp3's.  I'm thinking I could get both of these from a centos 
repository. What do you'all think?

If so, could someone point me to the correct repo(s) and the packages I'd need 
for playing mp3's?


Thanks in advance
