It's probably a pirate station, deliberately broadcasting on the same frequency. Contrary to FM modulation, with AM modulation two superimposed signals one the same frequency are demodulated as if they came from one transmission.
Swan Lake was played on UVB-76 in 2010 I believe and on other occasions previously. There have been other strange sound/musics broadcasted from this location so I don't think the pirate station makes sense.
