Audio parts of the CD (music & discussion) plays fine in XP or OSX machines (don't have a normal CD player to test there). As a bonus, the CD also has Hypercard software & a stack with visual extras--this runs on Mac OS 6-9(?), but not XP or OSX. You can listen to the audio CD which includes discussion of the music, but unless you have Classic or an older Mac you won't be able to look at the visual part.
