Basically, when you buy music from iTunes, it comes with a copyright protection called DRM. These DRM-protected songs are locked so that they only work with Apple MP3 players. That means that if you bought a Microsoft Zune, you cannot use iTunes music.

So, what is the solution? You have to burn a CD. When you do this, the DRM is removed (because the music is converted to a non-DRM-compatible media). After you burn the CD, you can rip it to your PC as an MP3 file which no longer has DRM.

1. Insert a CD-R or CD-RW disc into your CD-ROM drive.
2. Burn your playlist to make an "Audio CD". You cannot select the "MP3 CD" option since it requires the DRM protected iTunes music files be converted to (DRM free) MP3.
3. After the audio CD is successfully burned, insert the disc into your CD-ROM drive again. Then you can use iTunes to import the music tracks on the burned disc as MP3 files.

Alternatively, you can use TuneClone http://www.tuneclone.com . TuneClone makes a virtual CD-ROM drive, tricking your PC into believing that you are burning a CD. Therefore, the DRM is removed without wasting a CD. Below is the step by step tutorial using TuneClone and iTunes 9.0.2 to convert M4P to MP3.

Step 1. Download and install TuneClone

TuneClone is compatible with Windows XP, Windows Vista (except Vista 64 bit) and Mac OS X 10.5 or above.

(Windows Version | Mac Version)

Step 2. Create a new playlist in iTunes

Create a new playlist, and add the iTunes songs you want to convert to the playlist.
