No, really, I feel stupid for asking this:

So I buy a song from iTunes, and it arrives as an .m4p file. If I burn that onto a CD to be played in my car (which will play .mp3, .wav, etc.) it won't play.

Roxio won't find the .m4p and allow me to play it through its jukebox (.m4p is not a file extension I can select to have it locate).

If I go and just change the .m4p to .mp3 neither iTunes nor Roxio can find it.

Is there a way to convert the .m4p to .mp3?

I haven't searched the archives for this, so a thousand apologies in advance if it's been covered before.

Thanks in advance,

JP
