[Intro] [Authentic Japanese Showa Enka vocal performance by a mature Japanese female singer.] [Her voice is mature, sweet, slightly husky, intimate, and deeply nostalgic. She should sound like an experienced woman looking back at a world that once seemed dazzling and innocent.] [The vocal must remain unmistakably Japanese Enka beneath the restrained delivery. Use natural shakuri, subtle but clear kobushi, emotional melodic bends, deliberate ma, lingering phrase endings, and deep controlled vibrato.] [Do not belt unnecessarily. Do not compete with the relentless dance beat through sheer loudness. Let her voice float closely and clearly above the mechanical rhythm with quiet emotional authority.] [The contrast is essential: the beat is repetitive, physical, mechanical, and relentless; the human voice is warm, fragile, nostalgic, and bittersweet.] [Do not use J-pop, idol singing, R&B, soul, Western dance-pop phrasing, or theatrical vocals.] [Use a separate cold robotic voice for designated English lines. The robotic voice must be emotionless, synthetic, precise, and rhythmically integrated with the beat.] [Intro – begin with only the relentless kick pulse, electronic atmosphere, and cold robotic voice.] [Robot Voice] LIGHTS ON. BASS ON. THOUGHTS... OFF. [Beat enters fully.] [Verse 1 – sing softly and intimately. She is surrounded by heat, light, bodies and sound, trying to empty her mind.] レインボーライトに 照らされて 熱い音と 熱の中 何もかも忘れ 踊ってる 真っ白になって 踊ってる [Robot Voice – cold and quiet.] Turn off your mind. Turn up the night. [Verse 2 – add nostalgia. Use gentle shakuri and restrained vibrato. The memory should initially feel beautiful.] 遠くで見ていた あの光 眩しいくらいに 輝いて 近づいてみれば そうでもなくて それでも夢中で 追いかけた [Robot Voice] Everything was shining then. [Pre-Chorus – allow sadness to become more visible. Keep the dance pulse completely steady underneath.] 慣れてしまえば 見えてくる 知らなくていいことまで 見えてくる 綺麗なものだけ 見ていたかった あの日の私に 戻りたい [Robot Voice – emotionless.] I don't wanna know anymore. [Chorus – memorable, hypnotic and bittersweet. Do not turn into a huge pop belt. Let the melody become wider while retaining mature Enka bends and vibrato.] あの懐かしい 気持ちは何処に キラキラした思い出を 返してよ あの頃の気持ちは 何処に 何も知らない私を 返してよ レインボー レインボー 光で隠して 見えなくていいもの 消してよ レインボー レインボー 低音をもっと 何も聞こえなくなるくらい [Robot Voice – rhythmically repeat.] Dance. Dance. Dance. [Instrumental Break – hypnotic electronic disco groove. Keep the four-on-the-floor kick relentless. Use short robotic fragments as rhythmic elements.] [Robot Voice] NO THOUGHTS. NO WORDS. JUST BEAT. [Verse 3 – sing with greater resignation. She now understands that the old sparkle cannot truly return.] あまりに多くを 知りすぎて あの日の光は もう見えない それでも今夜も ここに来て 真っ白になって 踊ってる [Robot Voice] Erase it all. Just for tonight. [Verse 4 – intimate and slightly more desperate. The vocal should remain controlled rather than dramatic.] 周りの声なら 雑音だから ライトと低音で 包んでよ 正しいことなど 聞きたくない 余計なことなど 考えたくない [Build – increase the electronic tension while the vocal stays human and vulnerable.] もっと もっと 音を上げて もっと もっと 光を回して [Robot Voice] NO WORDS. NO THOUGHTS. JUST BEAT. [Chorus 2 – deeper emotional Enka phrasing. Let the final syllables carry longer vibrato while the beat continues without mercy.] あの懐かしい 気持ちは何処に キラキラした思い出を 返してよ あの頃の気持ちは 何処に 無垢だった心を 返してよ レインボー レインボー 私を隠して 今夜は何にも 見たくない レインボー レインボー 低音をもっと 胸の奥まで 響かせて [Robot Voice] Dance until the memories disappear. [Bridge – dramatically reduce everything except the kick, bass pulse, distant electronic atmosphere, and voice. Sing almost alone in the middle of the dance floor.] あの時に戻れないことなんて 言われなくても わかってる [Pause.] 時間は戻らない 私も戻れない [Leave space between every phrase.] そんなことくらい もう―― わかってるから [Robot Voice] RETURN TO THE PAST? [Short silence.] IMPOSSIBLE. [The beat immediately returns.] [Final Build – she stops resisting reality. Her voice gradually becomes stronger, but never loses its mature sweetness.] だから今は 何も言わないで ただひたすら 踊らせて レインボーライトが 消えるまで [Final Chorus – maximum emotional release without becoming modern pop. The relentless beat, nostalgic synths and mature Enka voice finally become one.] レインボー レインボー 光で隠して レインボー レインボー 低音をもっと レインボー レインボー 何も考えず 今夜だけは―― 踊らせて [Human Female Voice – whisper the English line herself for the first time. Sweet, intimate and accepting.] Just let me dance until the lights go out. [Outro – continue dancing rather than ending dramatically. Let the music gradually become distant.] レインボーライトが 消えるまで [Soft Female Voice] Dance... Dance... Dance... [Robot Voice – distant and fading.] THOUGHTS... OFF. LIGHTS... ON. DANCE.
