Don't get me wrong, this one was the hardest of the polls currently up. But after listening to these a few times over, To Zanarkand kinda fades away into the background. You're Not Alone doesn't do that.
Double post after thinking about it more: I just listened to them both once, thought of To Zanarkand, then listened again and made my decision
You're Not Alone is not only a good tune but highlights that one great moment in the game. If you haven't played the game, you might not vote for it because it no longer has the emotional attachment? I guess To Zanarkand is a bit similar, but it more encompasses the entire game. To Zanarkand is X. Melancholic, bittersweet. I think to me I'd vote for that one as well if I didn't play either game?
I guess because I feel To Zanarkand has more 'meaning' to it that I voted for it.
Also it fits my mood more. I much enjoyed listening to it today over You're Not Alone. More uh.... utility? To me anyways.
Might look janky because I edited some stuff I wrote in Discord, but yeah, there we go
