this is a kind of basic answer but its 1000% Undertale... it's such a heartwarming and emotional song and the way it perfectly encapsulates the story is just. ohhh it hits so hard. it makes me cry so bad i'm genuinely almost tearing up just thinking about it. it's such a perfectly crafted song too. the slow buildup of the instruments and melodies and the way they meld together creates just such a beautiful and pleasant sound.. it feels like a lullaby, the kind of song you listen to to get in both storytime and bedtime music, you know?

and also like. the way it PERFECTLY puts together the emotions of the story too. like. the emotions it brings out of me is insane i love that song so much. i genuinely don't think any other song from any game could ever compare to how significant Undertale is to me. it's so perfect in every way possible
