Sort music

So, over the years, I bought music from iTunes, Urge and Rhapsody, and all these files are mixed with my non-DRM'd MP3s, which I ripped from the CDs. Now some of these files have expired licenses, and some of them have valid licenses.

I want to sort music by the various DRM / license restrictions that they have on them. This will make it easier to delete music that I don’t have a subscription to, and everyone knows which files I can use to play the music player.

Does anyone know if this is possible in .NET / Perl / Python? Are there any libraries available to help me do this?

Do all files have different extensions? If so, then this may work (I wrote all this from the top of my head so that it would not be tested):

import os

music_dir = "/home/johnbloggs/music/" # note the forward slashes and the trailing slash
output_dir = "/home/johnbloggs/sorted_music/"

for file in os.listdir(music_dir):
     if file.find(".mp3") != -1:
          if os.path.exists(output_dir + "mp3"):
               os.system("cp " + music_dir + file " " + output_dir + "mp3")

     elif file.find(".wma") != -1:
          if os.path.exists(output_dir + "wma"):
               os.system("cp " + music_dir + file " " + output_dir + "wma")

     # etc

It is written with Linux in mind. If you really want to read the license type from within the file, it will be much more difficult.
