I don't think I quite get the same feel as in Spirited Away (probably because I never really watched that film in full as a kid, but I did see it play on Cartoon Network repeatedly---about as often as The Iron Giant, so it's probably good!), but I'm constantly impressed by Zack, so there's no surprise here; this is amazing! Nice and evolving dynamics; full use of the orchestra in their respective roles; evokes the feeling of both flying and a certain emotional tension, for me.
Though I must admit, I checked out the theme song to Spirited Away, and for a moment, I thought I was playing this ReMix, but at 2:52, I realized that there was a YouTube lossiness to it... I checked and forgot that I was playing the Spirited Away theme song. So maybe they really are that similar!
