It's a bit of a story, but...
I was in the marching band for three years in high school (tuba!), and our director always picked pretty awesome music for our yearly halftime show. My first year was music from Les Miserable, third year was pulled from The Lion King on Broadway. The second year, no one knew what the heck we were playing. It sounded cool, but we weren't aware that there was a theme. And we had NO IDEA why we had to spend time making this Earth prop that would be dragged out at some point.
Then in March, after the football and competition season ended, we visited WDW for Magic Music Days. And then the night we were at Epcot, it all made sense. Illuminations was our show. And our director had managed to keep it secret nearly an entire year so that the surprise would come that night while watching the fireworks as a group. It was actually very meaningful.
So yeah, I have Illuminations on my mp3 player.
