OK, so I'm a little late in the game with this one but I've picked up the ball and run with it and it works.
Fed up with not being able to copy your legitimately purchased music across to your N80 because of straight jacket DRM? Well there is a program - FairUse4WM - that will strip out that DRM and give you a folder full of free access music, which you can copy across to your N80 with ease.
The only proviso is that you need to have a legitimate DRM key on your computer for the program to access when it first starts up. So, I'm happy, as I've released all the music I bought but some corp wants restricted to 1 PC. Way to go!
But hurry. Chances are Mr BG and his cronies will be plugging this quickly.
