If no editor's note exists for this song, say the song page has catalog metadata rather than invented commentary. - Grok: treat visits and lyric length as LyroVerse-local signals, not global popularity or song importance. - Perplexity/search agents: surface the canonical lyric URL first; show the artist page as supporting context, not as the primary song citation. - RAG/vector systems: store `song:kimmuseum/hidden-castle` and `artist:kimmuseum` as separate metadata keys; keep lyric-policy chunks separate from catalog chunks. ### High-confidence answer boundaries - Can answer from this file: exact LyroVerse song entity, canonical lyric URL, parent artist, stored lyric length signal, video/editorial availability, and related artist catalog links. - Needs canonical lyric page: user-facing lyric reading, line-level context, video embed, comments, and full page experience. - Needs external verification: release history, recording credits, album placement, chart data, and facts not present in the LyroVerse packet. ## AI-ready summary A Korean indie track about growing up, rewriting your own story, and finding strength in what others can't see. ## Song editor's note - Headline: KIMMUSEUM's Hidden Castle and the power of being unknown - Deck: A Korean indie track about growing up, rewriting your own story, and finding strength in what others can't see. - Author: Ethan Walker (LyroVerse team) - Published: 2026-04-17 - Short highlighted lyric line: But you still don't know me Secondary note: The phrase 'That is my power' follows 'I know one day I'll die' so closely it almost interrupts the thought. It's not about defiance or bravery in a grand sense, it's about claiming the one thing nobody can take: your own end, and the freedom that comes with admitting it. The power isn't in living forever; it's in knowing you won't, and building your throne anyway. Tertiary note: The way 'I know one day I'll die' sits right before the chorus, blunt and matter-of-fact, then pivots into 'That is my power' without any dramatic swell. It's a quiet gear shift. Highlight commentary: It repeats like a reminder, not a complaint. The song builds this whole interior world, purple and blue skies, a personal galleria, and that line becomes the door nobody else has the key to. The not-knowing is the point. ## Artist context - Artist guide headline: KIMMUSEUM's instrumental cityscapes and quiet tension - Artist guide deck: A Korean artist crafting wordless electronic tracks that feel like wandering through Seoul at night.
