error CS0029: Cannot implicitly convert type void' to UnityEngine.AudioSource'

public AudioSource MenuMusic;

void Awake () {

		MenuMusic = GameObject.Find("Menu Music").GetComponent<AudioSource> ().Stop();
	}

I get an error:

error CS0029: Cannot implicitly convert type void’ to UnityEngine.AudioSource’

private AudioSource MenuMusic;

void Awake () {
    MenuMusic = GameObject.Find("Menu Music").GetComponent<AudioSource> ();
    MenuMusic.Stop();
}
