Removing DRM from protected audio
You'll need Windows Media Player, Deamon Tools or other virtual drive app and the Nero Fast Burning plugin

Open the protected track (or tracks) in WMP, choose "Copy to a CD or Device", check the tracks you want to copy and in the pulldown below "Items on device" on the top right, select "Nero fast CD-Burning plug-in", click "Copy" in the top right, this will bring up the Nero interface, where it say's "Current Recorder" select "Image Recorder" then burn.
Now mount your newly created image.
You'll see that you have a normal Audio CD mounted, from which you can rip the tracks to whatever format you want without having to worry about DRM.
This results in no loss of sound quality which you will no doubt get if you play your protected tracks and capture the audio with various recording apps. The above works with WMP 9, I haven't tried it on WMP 10.
