How to encrypt an mp3 file to DRM??

[cpt_azad]

My friend wants to know how he can encrypt an mp3 file with DRM protection (or w/e its called, digital rights management) so he can transfer to his cellphone. Any ideas/suggestions on how this can be achieved (and using what software)?

tell him to buy it off itunes or napster

I don't know how to do it.

Why would anyone in the right mind want to do such a thing?

There is no sane reason on this earth that a lone individual would need to use DRM.
