How to have an object in Unity 3D that stays in scenes and does not recreate

Question

I’m trying to find a good way to play background music in Unity 3D. I want the music to keep playing consistently through scene loads. Don’t Destroy on load is fine and works, but every time I load the same scene, it makes another music game object because the scene itself has the game object in it. How can I solve my problem? I am a “beginner” (kind of), so I would like code I can understand.

With help from a question on the unity forum, I think I have solved my problem. The link to the question is here...

The Best Answer is the one I’m using.

The code is this...

private static Player playerInstance;

void Awake(){
    DontDestroyOnLoad(this);

    if (playerInstance == null) {
        playerInstance = this;
    } else {
        Destroy(gameObject); // Used Destroy instead of DestroyObject
    }
}
