Turn the music all the way down, then you'll have a better chance at hearing it, cause it is really faint. No subtitles appear either. Usually you can do it twice, but the second time it is a little fainter, and doesn't last as long (probably because the AI is there, but it doesn't have any substance causing it to be invisible.)
