  "title": "Ghost Signal",
  "lyrics": "[intro]\n(Chords: Em - C - G - D)\n(Inst: Atmospheric synth pad, filtered trap beat enters slowly with a low-pass filter sweep, subtle vinyl crackle SFX)\n(Energy: Low, mysterious, setting a tense urban mood)\n(Sound-Design: A single, delayed synth pluck motif establishes the key)\n\n[verse]\n(Chords: Em - C - G - D)\n(Inst: Full trap beat kicks in with punchy kick, sharp snare, and fast 16th-note hi-hats. Deep 808 sub-bass follows the chord roots. Synth pad continues in the background.)\n(Vocal-Perf: Male English rap. Confident, rhythmic flow, mid-range timbre. Every word is clear and enunciated. Sits tightly in the pocket of the beat.)\n(Mix: Rap vocal is centered, slightly compressed, with a short delay. Beat is powerful and fills the low-mid range.)\nTwo floors above the noise I hear the static hum\nScrolling through your profile like I'm going numb\nWatched you post a story laughing with somebody new\nDeleted what I typed cause none of it was true\n\n[pre-chorus]\n(Transition: Beat simplifies, hi-hats drop out, leaving kick and snare. A synth riser starts to build tension.)\n(Chords: Am - G - C - D)\n(Inst: 808 bass holds longer notes. A filtered arpeggiated synth is introduced, panning left to right.)\n(Vocal-Perf: Female Mandarin vocal. Softer, more breathy delivery than the chorus. Conversational and questioning tone. Builds emotion towards the chorus.)\n我把所有证据删干净\n却在睡前把你名字默念一遍\n骗自己说这不算什么\n骗得越久 越不像自己\n\n[chorus]\n(Transition: Cymbal crash and impact SFX. The beat returns to full intensity.)\n(Chords: Em - C - G - D)\n(Inst: Full beat and 808. A new, brighter lead synth plays a counter-melody to the vocal. The atmospheric pad becomes more prominent.)\n(Vocal-Perf: Female Mandarin vocal. Stronger, clearer chest voice. Soaring melody with a noticeable leap on '凭什么是我先放手'. Emotionally direct and powerful. Natural vibrato on the last word of each phrase.)\n(Melody-Contour: Ascending phrase, peaks on the chorus hook, creating an anthemic feel.)\n凭什么是我先放手\n明明你先转身走\n凭什么是我先放手\n爱了那么久 算谁的错\n\n[verse]\n(Transition: Lead synth drops out, beat becomes slightly more sparse, removing some percussion layers.)\n(Chords: Em - C - G - D)\n(Inst: Beat focuses on kick, snare, and hi-hats. 808 is prominent. The panning arpeggiated synth from the pre-chorus returns subtly.)\n(Vocal-Perf: Female Mandarin vocal. Returns to a more narrative, rhythmic delivery. Clear and precise diction, conveying a sense of confusion and observation.)\n停电那晚我们靠在天台数飞机\n你说有些话藏久了会变成秘密\n我没追问 你没说完\n后来才懂 沉默才是最长的告别\n\n[bridge]\n(Transition: A low-pass filter is applied to the beat, making it sound distant. A reversed cymbal swell leads into the section.)\n(Chords: C - G - Am - Em)\n(Inst: The beat is heavily filtered. A lonely-sounding synth melody plays in the background. The 808 is replaced by a long, sustained sub-bass note.)\n(Vocal-Perf: Male English rap. More intense and slightly faster flow than the first verse. Builds energy back up for the final chorus. Delivery is desperate and dramatic.)\nYou showed up in my contacts as a name I can't erase\nFour months of read receipts and I still know your face\nI practiced being over it I rehearsed every line\nBut the signal never dropped and that fault is mine\nSo I'm standing in the frequency where you used to be\nStill transmitting to a frequency that won't receive\n\n[chorus]\n(Transition: Filter sweep opens up fully into a powerful drop. All elements come back in at full volume.)\n(Chords: Em - C - G - D)\n(Inst: The most layered section. Full beat, 808, pads, lead synth, and arpeggiated synth all playing. Female vocal ad-libs are added in the background.)\n(Vocal-Perf: Female Mandarin vocal. Maximum emotional intensity. Ad-libs are layered with delay and reverb, creating a wide stereo image.)\n凭什么是我先放手\n明明你先转身走\n凭什么是我先放手\n爱了那么久 算谁的错\n\n[outro]\n(Transition: The beat abruptly stops, leaving only a sustained synth pad and a final vocal echo.)\n(Chords: Em - C)\n(Inst: The synth pad fades out slowly.)\n(Vocal-Perf: Vocal phrases are chopped and repeated with heavy delay and reverb, fading into silence.)\n(Sound-Design: The sound of a heartbeat fades in and then fades out as the final element.)\nNo signal left\n凭什么先放手",
