Notes

• Short simple music (30s + minimal description) is likely to trigger copyright checks; it is recommended to enrich the description, add more parameters, or increase the duration
• Audio download links are time-limited; the script automatically downloads the file locally after generation
• BGM v5.0 does not require separate Genre/Mood parameters; describe them directly in the Text field
• Vocal songs v4.0 and v4.3 differ in the supported enum values for each field; see the parameter documentation for details
