How to make DontDestroyOnLoad stop duplicating game objects!

Unity Engine

I am using a DontDestroyOnLoad Script for seamless music in between scenes and 2 buttons (One too set.active and one to deactivate). When I deactivate the music game object and then go back the the home scene a new music object is created. Is there a way to stop this? Any help is welcome.
Thanks!

DontDestroyOnLoad Script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Music : MonoBehaviour
{
     void Awake()
    {
        GameObject[] objs = GameObject.FindGameObjectsWithTag("Music");
        if (objs.Length > 1)
            Destroy(this.gameObject);
        DontDestroyOnLoad(this.gameObject);
    }
}

FindObjectsWithTag will not find objects set to DontDestroyOnLoad as they are in their own special scene.

It sounds like you want a singleton. Do this and use Music.Instance to access the methods you want to use.

public class Music : MonoBehaviour
{
    public static Music Instance;

    void Awake()
    {
        if(Instance == null)
        {
            Instance = this;
            return;
        }

        Destroy(gameObject);
    }
}

Thanks for replying! This worked! However this brought up another problem. If I set the object as not active and then go the the next scene and then come back and try to set it active it says game object missing.
