Jack Watches Everything

I knew that Sam Anders was reciting lyrics from "All Along the Watchtower" from the moment he said "No reason to get excited," and I don't think he's a Cylon-- instead I think the four of them are hearing music broadcast from Earth, but I don't have anyone to discuss this with because the only person that I know who likes to talk about Battlestar Galactica is in Turkey (but I guess there's always Jack-- Jack watches everything).
