Sanctuary Voice of the Future goes dummy hoarde, and I vote for it as my #1. have a listen:
If we're going by official track mixes, then Sanctuary wins again just from being so delicious and nostalgic. Whenever I hear it, tears well up in my eyes and ears. It and KH2's Dearly Beloved just make me remember the peaceful times. Zero stress, stay home from school when sick, all of the good times. No Internet connection except to play RuneScape or AdventureQuest. Oh how I miss 2005-2006.
I would have voted maybe Ray of Hope or even FmF, but neither song fit the game they are featured for. Face my Fears has ZERO to do with KH3. Ray of Hope is the antithesis of 0.2 (especially after the fact that we learn Aqua's struggles meant literally nothing and she got darked in like 3 seconds). they are good songs don't get me wrong but they are in my opinion thematically irrelevant.
