I consider theme park fandom to have several 'levels' to it. First level is going to the parks and enjoying the time there, then it progresses deeper into collecting, research, and reliving the parks at home. Personally, I'm somewhere near level 12, where you write about them on blogs and forums and write historical articles.
But one of the first things most people find themselves wanting is theme park music. Previously, the only outlet was through officially released albums of varying levels of quality and depth. Sure, anyone can get "Grimm Grinning Ghosts" quite easily; but what about Papillon by David Arkenstone? Previously you'd need to scout record stores ready to spend $12 on one track. iTunes made this progressively easier to get, but now with Spotify large sections of park music is now available, for free, online.
Thanks to Kyle Crane, there is now a Spotify playlist of Disney Parks music. It has everything from the Tiki Room to "I Already Have a Husband" by Balafon Marimba Ensemble; 'We Are Here To Change the World' by Michael Jackson to 'Standing in Motion' by Yanni.
NOTE: The embed code for Spotify has been flaky, if this does not work, use this link instead.
