As far as I am aware (and <http://en.wikipedia.org/wiki/MP3> backs me
up), there is no DRM or other licensing mechanism available for MP3
files. Providers of DRM-restricted media use proprietary formats, such
as Apple's AAC or Microsoft's WMA, which are both capable of carrying
licensing information.

A little research suggests to me that this is going to be 'difficult'.
What I _think_ you have to do is get the Windows Media Format SDK from
<http://www.microsoft.com/windows/windowsmedia/forpros/drm/components.aspx>
(scroll down) and read the documentation in that about how to DRM
enable your app. I haven't seen a simple API call you can make just to
ask, 'Is the current user licensed to play this file'. There might be
one though.
