The Hills Are Alive With the Sound of Muzak?

If you'd asked us awhile back to think of a precursor to such newsy tech offerings as iTunes, Napster, satellite radio and BPL (broadband over power lines), we probably wouldn't have settled on Muzak.
...[T]he L.A.-based Architecture Urbanism Design Collaborative...says Muzak was originally intended as a kind of subscription service that would be piped into people's homes with the help of utility lines.

You know, every time I drive to Massachusetts or other points East, I pass the local headquarters of the Muzak Corportation on I-90 just east of Albany. I stopped in once and you know what they have playing in their elevators? Speed metal. Go figure.
