Seems like a jammer to me. With 27385 LSB though, you can never really tell. I would presume that if somebody was trying to broadcast they would try and find a clear frequency, and stations are continuing to call CQ and transmit in general even when the music is playing.
I sort of wonder why pirate broadcasters on 11 meters don't use frequencies like 26925 kHz or 26955 kHz. They're usually clear (well, usually), and are easy to remember since they're both 20 MHz above the common 6925 kHz and 6955 kHz 43 meter pirate frequencies.
