  "lyrics": "[intro]\n(Chords: D#m - B - F# - C#)\n(Inst: Clean electric guitar plays a lonely, pentatonic melody with heavy delay. Bass and atmospheric pads provide a sparse foundation.)\n(Mix: Guitar is front and center, creating a vast, empty space.)\n(Melody-Contour: Lyrical, descending pentatonic phrase, establishing the 'wanderer' mood.)\n\n[verse]\n(Chords: D#m - B - F# - C#)\n(Inst: Full drum kit enters with a slow, steady rock beat. Acoustic guitar strums, clean bass plays root notes. Piano adds soft chords.)\n(Vocal-Perf: Husky, conversational chest voice. Every syllable is clear and emotionally direct. Storytelling delivery.)\n一个人在苍茫的大地飘来飘去\n一个人在无尽的期待里承受风雨\n挨不过草原的冬季\n思念就在北风里死去\n\n[chorus]\n(Transition: Drum fill and cymbal swell build energy.)\n(Chords: D#m - B - F# - C#)\n(Inst: Distorted electric guitars enter with powerful, sustained chords. Drums are strong and driving with crash cymbals. Bass is solid.)\n(Vocal-Perf: Voice shifts to a powerful, strained, high-range delivery. Strong emotional release, especially on the repeated '草原'.)\n(Melody-Contour: Wide interval leap on '知道', creating a memorable peak.)\n草原草原草原你可知道\n你可知道我的孤单\n我在梦中日夜思念的人儿\n何时来到我的身边\n等春风迎来了蓝天\n吹红了鲜花吹开我的笑脸\n\n[interlude]\n(Transition: Vocal ends, leaving the distorted guitar ringing.)\n(Chords: D#m - B - F# - C#)\n(Inst: Epic electric guitar solo. Blues-rock influenced, using pentatonic scales with long, sustained bends and heavy vibrato. Full rhythm section provides powerful backing.)\n(Mix: Guitar solo is the main focus, mixed loud and center.)\n\n[bridge]\n(Transition: Solo ends, dynamics drop slightly. Distorted guitar becomes cleaner.)\n(Chords: D#m - B - F# - C#)\n(Inst: Piano becomes more prominent, playing arpeggios. Drums are less intense, focusing on hi-hat and snare.)\n(Vocal-Perf: Delivery is questioning and reflective, setting up the final chorus.)\n雪山雪山雪山你可明白\n你可明白我的爱\n\n[chorus]\n(Transition: Massive drum fill and crescendo into the final chorus.)\n(Chords: D#m - B - F# - C#)\n(Inst: Full band at maximum energy. Sweeping synthesized strings re-enter, adding to the epic feel.)\n(Vocal-Perf: Most powerful and emotional delivery of the song. Voice is on the edge of breaking with raw feeling.)\n(Highlight: The resolution in the lyrics from 'longing' to 'warmth' is matched by the musical climax.)\n我在梦中日夜思念的人儿\n她何时能回来\n等阳光融化了冰霜\n融化了寒冬就温暖了牧场\n\n[outro]\n(Chords: D#m - B - F# - C#)\n(Inst: Song fades out with the main electric guitar soloing over the rhythm section, repeating melodic fragments from the interlude.)\n(Mix: Slow fade to silence, leaving a final, sustained guitar note with feedback.)",
