 An additional question.  Do CD's ever contain tracks that are not in the
 directory?  There are allways copyright disputes when it comes to music
 and it sounds convienent if one should come up at the last minute to
 delete it at the directory level, but leave it on the disc, since all
 consumer machines would not know of it.  I also see the possibility of
 special "bonus cuts" just for hackers.  Does anybody know of any tracks on
 any CD's that are there but not playable on a consumer player?
