How to destroy a game object marked "DontDestroyOnLoad" when a new scene loads?

Question

So I created a music player to play music through all my menu and story scenes without interrupting, but then in my game scene I want to delete that music. How can destroy the playing music when my game scene loads?

Here is my music script:

#pragma strict

var offsetY : float = 40;
var sizeX : float = 100;
var sizeY : float = 40;

var musicPrefab : Transform;

function Start () {
    if (!GameObject.FindGameObjectWithTag("MM")) {
        var mManager = Instantiate (musicPrefab, transform.position, Quaternion.identity);
        mManager.name = musicPrefab.name;
        DontDestroyOnLoad (mManager);
    }
}

Answer 1

Just call destroy on it directly:

Destroy(mManager);

DontDestroyOnLoad only protects the object from being destroyed when loading a new scene.
