Anons, here's a guess as to what Q meant in #2261:
>MUSIC IS ABOUT TO STOP.
>202-456-1414
>Q
The phone number connects you to the Whitehouse switchboard. The following excerpt comes from a NY Times article in '83:
>…The small room is almost completely filled by the 10-position Western Electric switchboard. It is the old-fashioned kind, with operators using black and red wires that plug into holes corresponding to the 5,000 telephones within the White House complex. The board has been in use since l963, when it was installed to handle the heavy flow of calls that followed the Kennedy assassination. It is somewhat outdated, according to John F.W. Rogers, Deputy Assistant to the President for Management.
>The White House has no plans to update the hardware, however. The current board allows the operators to see who is talking to whom, information that is vital when the President wants to interrupt a call. More advanced systems simply flash numbers on a screen, said Mr. Rogers, preventing operators from keeping track of who is on which line.
>Somewhere in the office are the file cabinets full of the thousands of private numbers the operators use to locate their prey. The precise location of the cabinets is a secret, as are their number and the color of the cards on which the numbers are printed. People give them those numbers with the guarantee that they will be kept confidential, the operators say, and they are.
>In fact, not even former Presidents can breach the security of the phone room. When former President Carter left office two years ago, his secretary, Susan Clough, called the switchboard and asked for certain numbers so that the President could keep in touch with other world leaders via their private lines. The request was denied. A compromise was reached allowing the former President to call the switchboard whenever he needed help in locating someone, an arrangement Miss Clough says he uses to full advantage.
…
>The phone number files aren't the only closely guarded secret in the switchboard office. The operators agreed to be interviewed only if their names were not used and if they were not asked questions about the current Administration. Their professional techniques, such as how they verify whether a call is legitimate and the proceedure they follow in the event of threatening calls, are secret. How they voted in the last election is also secret, but for different reasons.

So what if someone in that office was "singing" about phone calls made by POTUS and his cabinet? Clearly there have been leaks along those lines. My guess is they found the culprit, and removed him/her. Music stopped.
