If you want to remove the DRM licensing of your mp3’s that you buy from Itunes or Napster use Sound Taxi to get the DRM out. I have used it before for at least 3 years and it works.
I just download a song from napster not the 30 second clips then I use Sound Taxi to get rid of the the DRM and copy over to my mp3 player thats it.
The serial number is a corporate license so you can use it. Just copy the Serial number then hit the click actvation code and thats it fully loaded no patch work nothing.
Enjoy Peeps
