If they don't want to do the Wonderland Music kiosk at the parks, the at least let us purchase them through the Disney website - but that would make good business sense and probably a few bucks for the mouse, so let's not hold our breath.
I don't think it would make any business sense at all. You're assuming that there are millions of Disney fans who would want a complete collection, but there aren't. Did you buy all the Wonderland kiosk CDs? I sure didn't, and there's no way in heck that I'd even consider it, even if I were obscenely wealthy.
Disney has a much better idea of how these suckers would sell than we do. Seriously, I'd bet large sums of, uh, whatever I have large sums of, that a good many of their so-called "classic" titles wouldn't sell more than a few hundred copies worldwide grand total. Or are you really going to tell me with a straight face that you would be willing to shell out $18.99 for a CD of nothing but multitracked accordion music? Disneyland released an LP that was exactly that. WDL-3029. It even has an ugly cover.
Selling CDs online requires infrastructure and inventory, and having them pressed requires a minimum order of 1000 discs (and you don't get the volume rate for that quantity, let me tell you). Plus you have to sell enough to cover mastering, packaging, promotion, royalties, documenting and administering said royalties, storage and handling, creating the writeup on the website and about a bazillion other things that I can't imagine because I don't work in mail-order fulfillment. Selling CDs in a theme park where they can be "manufactured" on demand makes a bit more sense, and selling them as automated downloadable files online makes even more.
It also makes sense to press small runs of the most popular titles and sell them at the parks, minus the kiosks (perhaps under a sublicensing deal with a smaller music company). I expect we'll see that happen. Be patient.
Disney is still one of the only two significant catalogs of American children's records with many titles still accessible for purchase (Sesame Street is the other). The kiddie catalogs of RCA Victor, Capitol, Columbia, Decca, Mercury, Golden, CRG/Young People's, Peter Pan and Hanna Barbera all contain material as good as or better than anything Disneyland Records ever did (and some of it is Disney material). Nearly all of it is moldering in the vaults, unavailable anywhere. That's what you ought to be whining about.
