First off, I love the music of John Williams (he wrote all the marches you're hearing) as well as Gustav Holst's THE PLANETS..... but it just feels really forced in this area.
All of the music at DCA feels really forced actually. There's no area that offers the natural sounds of the attractions in the area. It's kind of a quality trait that most don't think of, but it's certainly a feeling that isn't as comfortable as Disneyland.
Do we really need to go searching through that site? Let's provide folks with actual places to legally download or purchase the music.
Next time I go to DCA, I'll sit there and write down all the songs they play. I have all the songs they play from assorted cds that I've bought through the years... I just don't remember which ones they are right now.
