Your comment reminds me of how Disney fans found new ways to enjoy the parks with the evolution of the internet and technology. Many of us enjoyed the parks as children or young adults long before YouTube, so you can imagine our joy when cameras and video cameras became more accessible and virtually everyone gained access to online photo and video sharing. Even as recently as 10 years ago, Disney fans had to hunt down other fans and amateur archivists or one of the very few small business-type "clubs" who published home-made DVDs of a Horizons ride-through, Kitchen Cabaret show, etc. Now, all the glory of WDW nostalgia, and the latest and greatest refurbs, are just a mouse click away. Hmmm, maybe that's why it's called a MOUSE click?
For me, Napster (the original version) opened many doors into the world of the Disney parks. I was able to find tons of attraction recordings, spiels, soundtracks, audio loops, sound effects, etc. that appeared to be "ripped" directly from the master recordings, and not second-hand recordings of in-park playback. I don't know how or where the people "sharing" those .mp3 files obtained all of that material, but it was a great way to explore and re-live much of the magic of WDW.
I imagine that, for many people, the "Disney bug" bites before they even make it past the turnstiles.
