I think it's probably got something to do with the use of trumpets, and the chorus voices. It also feels kind of majestic; as though a sealed pumpkin carriage suddenly exploded, releasing showers of brightly coloured confetti and white doves into the air. (I don't know how I manage to conjure up that type of imagery- there hasn't yet been a Disneyland parade I've seen that's resulted in a pumpkin carriage exploding, even if it's for confetti showers)
Well-- that's just what I imagined- when I listened to the soundtrack, it felt like I had a glowing golden orb inside me that was just so eager to burst out into a million golden shards; glittering particles amongst the bright sky.
