Musical delusions

"Using the principles that generate these illusions, we can now produce music that sounds radically different from one listener to another." (http://deutsch.ucsd.edu/psychology/pages.php?i=201#Technical.php)

And composers not knowing these principles run the risk of doing the same i.e. create music that sounds differently across listeners. Hmm... wait, does not any music sound different across listeners already?
