I found a really good remix made by a youtube user for this amazing song:
This one is surprisingly good! It captures the calm emotion well even though it's a rock remix (which I often do not prefer).
And have you guys heard the official piano collections?
I learnt this song a year ago or so. I personally love the improvisation in the middle.
Let's not forget the official orchestra version too!
This one is lovely. The choir is priceless.
What do you guys think? Any other versions you would like to share?
