http://www.laatedaa.com/2008/09/23/how-to-remove-strip-drm-off-itunes-music-tutorial/The tutorial shown below is for users who is annoyed by iTunes DRM and wants to strip it off because they want to play it in other devices, use it as background music in a home video, or anything else that DRM limits it to do. Many people know you strip off the DRM of iTunes music by simply burning the song to a CD, and ripping it back over, losing very little quality (if settings are correct). This method does the same exact thing but you will not need a CD-RW disc, a CD ROM drive, or even need to burn anything! It’s that simple. Let’s show you how to perform this.
We are going to be using a program called TuneClone. TuneClone is basically a program that acts as a virtual CD drive that allows you “burn” MP3 from iTunes and “rip” it. TuneClone “lies” to your computer saying that you have a CD-RW drive that it will burn to (like Alchohol 120%).
Step 1
-Download TuneClone from
http://www.tuneclone.com and install it.
It is fully compatible with Windows XP and Vista. A virtual CD Burner will be installed. This virtual CD-RW will be used to convert music files.
Step 2
Set the default CD Burner to TuneClone CD-RW at iTunes.
Click menu Edit, select menu item Preferences…, and then select Advanced Tab. In order to keep the artist and title information of the music, the Include CD Text option should be checked.

Step 3
Create a playlist, and then add the files you want to convert into the playlist.
Step 4
Click Burn Disc button at the bottom right of the main screen of iTunes.
While the burning gets started, TuneClone will automatically convert the music file to either MP3, WMA, or WMV.
The most important step is to choose the cd burner. Then the software can convert the music files automatically. This is the easiest way to strip / remove DRM off iTunes music for personal use!
