You've got to wonder why MS is interested in this at all. They have no stake in any music company, from labels to studios to distributors, as far as I know. It's not like they really need to prop up their OS in that industry, not that this would help that particular thing.
The only thing that this does is help remove features for their actual customers. And that's only going to piss people off. I can't imagine that anyone's going to say ``Yay! Now I don't even have the option of copying the music in any other way!'' Any person who's interested in not breaking the law (from their point of view) is just not going to do it in the first place. I don't believe that anyone could possibly be holding the position that copying music off of your CDs for personal use only is currently wrong, and that this will give them license to do it.
