We make music, and we must have made it so perfectly, because a song that I haven’t heard in five years or more began playing and I could repeat it word for word. A little prompting needed for the second verse, sure, but from then on I was singing too. All of these songs, their melodies and lyrics are tendrils racing in through our ears and weaving such strong memories, unconscious memories, tying neurons together and stamping them firmly that years later we can conjure them up again.

Sarah Blasko, Perfect Now, for reference.
