mp3 utilities

[Michael Satterwhite]

I'm going to need to transfer some tracks from my "Music For Magicians" CD to 
an MP3 player. I really haven't worked with hardware MP3 players, so assume 
that my knowledge on this is a little less than rudimentary.

What tools am I going to need to do this in Linux?  I'm assuming the player 
will come with software for Windows, but booting Windows is something I don't 
like doing.

Secondly, I'd like to add some voice-over to a few of the tracks that I 
transfer. What tools will I need for this?

I appreciate the help.
