Enable Audio CD writing in K3B

if you prefer then just open a terminal and
perform a

#yum install k3b k3b-extras-nonfree

and job done.

In Ubuntu you may only need to Run the following code in a terminal:

sudo apt-get install k3b libk3b2-mp3

- unsure as to whether you need the
other stuff (or similar), above?

Now when you run K3B, your system configuration should get the all clear and you can burn your MP3’s using your chosen method.
