Keys are useless (Score 1)

This will never work. Having this kind of protection on such a freely distributed media such as music, will only cause the h4ck3r community to work around it, or, consumers will not buy it at all. There is always the chance of forgetting keys, or other issues like that, that consumers will not want to be bothered with. After all, it's just music, not top secret US government files. I don't think the music industry is ever going to with this battle with the current strategy they are using.
