How do I copy DRM protected MP3's to audio CD?

[any ANONYMOUS forum user]

I have a bunch (about 700!) of DRM protected MP3's in a folder that I would like to burn to CD so my Dad can listen to them.
I downloaded them LEGALLY and paid for them however since then I have had a system failure and they appear to be locked, (Says I need a certificate to listen to them which I have no idea about!) They were downloaded from several sites and I cannot remember login details (or be bothered!) to get them again.

Is there a FREE software that will burn these DRM encrypted MP3's to CD??

I am not a freeloader trying to hack illegally downloaded MP3's before anyone jumps to conclusions! Like I said they were paid for by me!! )

MP3 files don't have any DRM protection. You can burn them to an Audio CD using freeware ImgBurn.

If you have DRM protected files (not MP3), you can try to remove DRM from them.
