In order to achieve the NULL playlist you could have a playlist with one song which is silent.

Or better yet -- make it that sound TV stations play when they've stopped airing for the day, for some extra nostalgia.

Ah but that would keep the audio devide alive, and my headphones )both the wired pair and the bluetooth pair) would keep emitting that white noise.

But that's only a problem if I want to keep them in. Otherwise Cage's 4'33" might well do ;)
