Question about DRM

Is it possible to decrypt or unprotect DRM mp3 files, off tracks you haven’t bought. Because my friend sent me a mp3-cd of tracks he bought on iTunes. But it won’t let me play the songs. I can’t ask him for the password or anything because he is on vacation. So is there a way around this?

If they are MP3 format they aren’t encrypted and you have another problem. If they are in iTunes native format and you don’t have the key on your computer, sadly there’s no way. That’s why they have DRM, after all. Tell him to buy them as MP3 from Amazon next time.
