ok, then let me rephrase...
I don't have an mp3 player, I have an old fashioned cd player, which I go to sleep with, can I make a normal cd out of the mp3's I bought without them losing any properties?

Can I record the mp3's into a cd for the car or for my discman?
Or does the effect wear off?
When I say record I mean not in MP3 but rather in a "normal music" cd
