I can't disagree with 'The Circle of Life' - a real blockbuster. I love the songs from The Little Mermaid, especially 'Under the Sea' and 'Kiss the Girl'.
It's the parks' music which really moves me, though. I'm convinced it's the music which makes parades - I love 'It's Time to Remember the Magic' from the Magical Moments parade and 'Jammin' in the Jungle'. I'm sure that's why I was underwhelmed by Share a Dream Come True - uninspiring music. Also love all the rides' music, in particular, Yo Ho (A Pirate's Life for Me), Everyone Has a Laughing Place, Grim Grinning Ghosts and There's a Great Big Beautiful Tomorrow.
I adore all the music from the Millennium Celebration, which includes what I think must be my absolute favourite, 'Tapesty of Nations'.
