That is a perfect analogy for something demonstrated in an earlier portion of the Closer to Truth episode where a very familiar tune is played but it has been altered to randomly assign each note to an octave above or below it. It is unrecognizable. Then they play it unaltered after which you hear the altered version once more and it can be recognized. You hear it differently with the added knowledge. It is also why they find people from different cultures will have different emotional reactions to the same music.
Expectation and musical perception
The PBS series "Closer to Truth" did a episode on "How Do Human Brains Experience Music?"

in which they explained the complex pathway by which the brain turns perception of sound into recognizable speech or music. Most significantly Prof Elizabeth Margulis of Princeton states that prior knowledge in the brain actually changes what we perceive when listening to music. The whole show is worth watching but at least check out her segment around the 23 minute mark.
What I get from this is that when listening to music the issue of expectation bias is HUGE. If the brain is expecting something it can open the door to hearing it, and the reverse is also true.
I see relevance here to the many on-going discussions on this forum. What do you think?
