One of the things that I dislike about downloading music from iTunes is that there is DRM present in the file.

If you rip a CD using iTunes and set it to rip as an mp3, you get a file that is infinitely copyable. If you download from iTunes, you have a limited option. And the problem with this is that if you get some corruption of the original file for some reason, you have no alternative but to purchase the song again.

Here is a handy little widget that fixes that problem. Doubletwist extracts the DRM code from the files making them easy to synch with an infinite number of devices. It was developed by the same guy that broke the encryption on the DVD.
