场景十二：Add Vocals

{
  "mv": "chirp-bluejay",
  "tags": "A smooth, soulful R&B track with a moderate tempo and a relaxed, laid-back feel. The instrumentation features a clean electric guitar playing arpeggiated chords, a prominent bass guitar providing a walking bass line, and a drum kit with a soft, brushed snare sound. The male lead vocal is smooth and melodic, with a baritone range and a slightly melancholic tone. The song is in a minor key, contributing to its introspective mood. Production elements include a subtle reverb on the vocals and guitar, creating a spacious and intimate atmosphere. The song structure follows a typical verse-chorus format with a clear melodic progression.",
