On the contrary, they do have a few cd sets of certain attractions, such as COP, Haunted Mansion, People Move and the PIrates.
I own three of these sets.
I also know of a guy who sells cd's of everything you can think of Disneyland. I have a number of these cd's , which are awesome. They include the Main Gate Music (old and new versions), Pardi Gras parades, Christmas parades, Adventure thru Inner Space, America the Beautiful, just to name a few.
