Ahh. I was wondering what the unit was doing there. Maybe with mine it started playing the song to it's self to see if I was feeding it anymore weird music. But then it realized I was watching, timetraveled to erase it's log of doing this, and had a problem.
(I personally love some of the error messages the unit will shoot out it's serial port from time to time. I'm still wondering if the "Go away, you don't exist" one is part of shutdown, or something the empeg people put in)
