I know you can get the Indy Soundtrack without the dialouge on some Disneyland CD. If you search Best Buy enough, you will be suprised to find some Park CDs.
Anyway, I would like them to put it on I tunes, especially their holiday CD.
Thinking about music at the parks, one of the more popular songs played on Main Street USA in WDW is "Put On your Sunday Clothes" from Hello Dolly. Well most kids walking in now know it as the "Wall E Song" since it is the opening song of the movie. Been at the MK in the background music forever and now because of Wall E, it becomes more reconizable (which I think is something amazing you can take from Wall E making the song somewhat popular again)
