1. 首先给目标物体添加Audio Source组件
2. 新建Script脚本，代码如下

using Spine.Unity;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class yateland : MonoBehaviour
{
    public AudioClip[] audios;
    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(Audio());
    }
    // Update is called once per frame
    void Update()
    {

    }
    IEnumerator Audio()
    {  
            for (int i = 0; i < audios.Length; i++)
            {
                this.GetComponent<AudioSource>().clip = audios[i];
                this.GetComponent<AudioSource>().Play();
                yield return new WaitForSeconds(audios[i].length);
            }
    }
}

3. 将脚本挂给物体
4. 输入播放音乐段数
   
5. 拖拽音乐到下方
