Excellent advice by Rentzsch:
When iTunes Music Store first came out I studied it and decided to buy music off it. Not because I trusted Apple, but because I had a space Mac that I could use as a DRM lifeboat.
I copied my purchases as I made them to the old Mac. The Mac was also disconnected from the Internet after its initial authorization. Finally, I had software in place to extract the audio I purchased even if Apple pulled the DRM football from me just as I tried to kick it.
Fortunately Apple’s iTMS DRM dog never barked. But after today’s Amazon Ebook controversy I decided it’s time to share my similar Amazon Ebook Insurance Policy…
