For me, it's all about the things that were happening in my life and the season during the time I fell in love with the music. Certain albums take me back to where I was working during a particular summer, or who I was hanging out with a lot while I listened to it, etc. Because of this, I end up with lots of "Summer albums" and "Winter albums", and they only feel right to me when I revisit them during their "season".
ANd this song in particular makes me visualize jumping up into the sky, approaching the end of Earth;s atmosphere and orbiting the planet while I float backwards and watch all the countries and continents passing by over and over again and thinking to myself "How awesome that I have found a way see the entire planet in just a few small seconds with my own eyes". It's powerful shit and makes me feel really tiny and insignificant, but also reassures me that I am everything and all that I need. I love it.
