I'm drunk now, so I feel I can comment more freely on this piece.
At the point in the movement you mention, I've always pictured it as a snapshot of my own life. At the beginning, you are clueless and kind of dumb. As you grow, you start to awaken. Finally at the end of the movement, you realize the majesty of the world around you and respect it's true beauty and revel in it, like a man looking down from the mountaintop on all of God's creation.
I've performed this movement many times in public. I'm a traditional man who doesn't cry or any of that baby shit, but hearing and performing Jupiter always chokes me up a bit. My only issue with the version you posted is that the largo portion of the movement was too up-tempo and not milked enough. Slowing it down a touch really makes it more effective. Mars is by far the most fun to perform.
I've also always loved Aaron Copeland's "Fanfare for the Common Man"
It's a ridiculously simple piece to perform but it's incredibly powerful
and my all time favorite is Antonin Dvorak's "New World Symphony"
The whole thing is great (including Karajan, the cardboard-stiff conductor), but the really great part starts at 32:00. For those of you who don't know, Vienna is the Cooperstown of classical music.
