I would vote for some music from Final Fantasy, but for more specific i guess i would give my bet on Flower of Blooming in Slum by Nobuo Uematsu. Have seen many versions of it and it is always good. The OST is always remind of me Aerith and that is what making me sad when listening on it. BTW, the OST playing on new trailer of Mario Odyssey looks pretty great. I really love the beat.
