Oh, No problem, they listen to what I pay for. Actually, one of my kid's has a band-might take a look on Napster-Ira's All Stars.
More to the point though, your argument is cogent. The setup I have allows each/several/all zones to have different sources of audio-including admonishing WAV files. I intend to have the audio input in each zone tailored to that usual occupant, thereby inflicting my personal favorite-Ludicrus on all but my mother-in-law-nah, she needs a dose too. Since I have "drawn time and date" in Crestron, the time of day and day of the week can also be useful for hall entry music, for example, when the little rascals arrive from school. The programming will have logic that makes the occupant(me) of the MAster bedroom's egress superscede any audio surces in operationBe certain, when I am around Barney will be muted. Come to think of it, nothing purple is allowed in MY house, except ocassional rain.
Nothing like a little fun at the old shack.:-)
BTW, RAdio Ra was fairly simple to install and integrate into Crestron.
