Aah, thanks for your explanation! I totally know what you mean - I also remember songs trying to incorporate an uplifting, hopeful section, like 'Pokemon Diamond/Pearl, Dialga/Palkia theme' or 'Zelda Spirit Tracks, Fighting Cole and Malladus'. Not sure if these sections actually use major chords, but they feel hopeful rather than hopeless. It's mostly final bosses that seem to do this in my experience. I'm down to try this sometime, it seems quite interesting! :D
