Radio Daze - The Consumerist notes that the XM and (less-so) Sirius changed programming after their merger with little advance warning to subscribers. This explains why my old disco channel (yeah, that's right) is now something called "The Foxxhole" which is mostly "comedians" yelling into a microphone. I seem to recall another time when a radio station changed formats on the fly. That didn't work out as planned, either.
