Many people will have many different media apps that they use over the course of their PC's lifetime. Its completely unreasonable to expect them to find each and every app that uses this, and then find out how to turn it off for each app separately. Its unacceptable that this "feature" can't be turned off globally. Its a pretty blatant hole in privacy. PC is "locked", but any random person can come and browse your music collection.
Hopefully this gets fixed. Hate this new trend of "ooh lets add this shiny new feature" without a single thought about what the side affects are.
