  "lyrics": "[intro]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Solo grand piano playing a simple, melancholic motif based on the chorus melody. A touch of lush reverb.)\n(Mix: Centered, intimate, spacious.)\n(Melody-Contour: Gentle descending line.)\n\n[verse]\n(Chords: Cm - Ab - Eb - Bb)\n(Vocal-Perf: Conversational, gentle chest voice. Mezzo-piano. Clear diction with minimal vibrato.)\n(Inst: Piano continues with simple chords. A subtle, clean electric bass enters, holding root notes. A simple kick drum pattern on beats 1 and 3.)\n(Mix: Vocals remain front and center, piano and bass create a warm bed. Still intimate.)\n(Transition: A soft string pad swells quietly in the last two bars.)\n话总说不清楚\n该怎么明了\n一字一句像圈套\n\n[pre-chorus]\n(Chords: Ab - Ab - Eb - Bb)\n(Vocal-Perf: Intensity builds slightly. A sense of urgency enters the voice. Dynamics rise to mezzo-forte.)\n(Inst: The full drum kit enters with a driving backbeat on the snare. Hi-hats play steady 8th notes. The string pad becomes more prominent.)\n(Mix: The stereo field begins to widen. Drums add punch and drive.)\n(Sound-Design: A subtle reverse cymbal swell leads into the chorus.)\n旧账总翻不完\n谁无理取闹\n你的双手甩开刚好的微妙\n然后战火再燃烧\n\n[chorus]\n(Chords: Eb - Bb - Cm - Ab)\n(Vocal-Perf: Full power, soaring tenor in a higher register. Sustained notes with controlled, emotional vibrato. Forte.)\n(Inst: Full band explosion. Wide, powerful piano block chords. Soaring, distorted electric guitar plays melodic fills in response to vocal phrases. Drums are powerful and driving.)\n(Mix: Stadium-sized width. Lush reverb on vocals and snare. Guitar fills panned wide.)\n(Melody-Harmony: Strong, anthemic melody focusing on chord tones.)\n我们背对背拥抱\n滥用沉默在咆哮\n爱情来不及变老\n葬送在烽火的玩笑\n我们背对背拥抱\n真话兜着圈子乱乱绕\n只是想让我知道\n只是想让你知道\n爱的警告\n\n[bridge]\n(Chords: Ab - Eb - Bb - Cm, Ab - Eb - Bb - Bb)\n(Vocal-Perf: A dynamic drop. Vocals become more tender, almost pleading, with an airy quality. Builds back up at the end.)\n(Inst: Arrangement strips back to just piano and the lush string pads. Bass holds long, sustained notes. Drums drop out completely.)\n(Mix: Space opens up around the vocal. A very wide, cinematic feel.)\n(Transition: A powerful, rolling drum fill brings the full band back for the final chorus.)\n我不要\n一直到\n形同陌路变成自找\n既然可以拥抱\n就不要轻易放掉\n\n[chorus]\n(Chords: Eb - Bb - Cm - Ab)\n(Vocal-Perf: Maximum emotional intensity. Vocals are pushed to the edge, with tasteful ad-libs and runs over the main melody. Fortissimo.)\n(Inst: Everything from the first chorus, but bigger. Cymbals crash more frequently. The lead guitar part is more aggressive and constant. A high string counter-melody is added.)\n(Mix: The biggest point of the song. All elements are loud and clear, heavily compressed for maximum impact.)\n我们背对背拥抱\n滥用沉默在咆哮\n爱情来不及变老\n葬送在烽火的玩笑\n我们背对背拥抱\n真话兜着圈子乱乱绕\n只是想让我知道\n只是想让你知道\n这警告\n\n[outro]\n(Chords: Cm - Ab - Eb)\n(Vocal-Perf: The final two lines are delivered with a sense of resignation, fading out with a long reverb tail.)\n(Inst: The band cuts out, leaving only a final, sustained piano chord and the reverb tail of the last cymbal crash.)\n(Mix: Rapidly decays to silence, leaving just the vocal and piano reverb.)\n只是想让我知道\n只是想让你知道\n爱的警告",
