AppleID is embedded in songs purchased with DRM-free "iTunes Plus"

Apple is JapaneseITunes StoreBut DRM-free "256 kbps" at 200 yen per songITunes PlusAlthough it started, although it is DRM free, it is dangerous to give the downloaded file to a friend as it is, or even distribute it on the file sharing software.

The reason is that songs purchased with "iTunes Plus" are embedded with AppleID at the time of purchase. In other words, if you look at it from Apple, you know who was the one who let you out.

So, I tried to actually purchase it to see if AppleID was really embedded.
The following blog I first discovered this.

First, after installing the latest version of iTunes, access the iTunes Store. I will sign in to make it available for purchase from iTunes Plus. It is what "gigazine" is displayed in the upper right of the image below.


Click "Buy"


Purchase complete, you can play properly


In the case of Windows Vista, there is a folder called "iTunes" in the music folder, and the music file purchased is included in it. In order to verify whether it is really DRM free, I tried playing this file properly by putting it in Winamp. It is DRM free without problems.


However, when opening the file with a text editor, binary editor, etc., inside it is embedded the AppleID at the time of purchase like this. Truly it is not DRM free but even AppleID will disappear ...
