update: I was unfair. this text appears only for the paper edition on the amazon web page, and not for the kindle edition
"The audio CD is playable on any CD player, and also enhanced so PC and Mac users can adjust the recordings to any tempo without changing pitch!"
but it is easy to get confused. the text changes as you tap either " kindle Edition" or "paper edition" boxes, and that sentence pops in and out. the test of the text is the same
so the dead tree + coffee cup platter edition has more features than the
enhanced kindle edition
