How to save boolean to player prefs in Unity?

I’m making a player settings thing where the user can turn off or turn on the game music by clicking buttons. I had this script below and everything was working fine.

 private GameObject music;

 public void Start()
 {
     music = GameObject.FindGameObjectWithTag("Music");
 }
 public void YesButton()
 {
     music.SetActive(true);
 }

 public void NoButton()
 {
     music.SetActive(false);
 }

I want to save it as player preferences so when they go out and back into the game, their settings would be saved. How would I do this? This is what I tried:

 private GameObject music;
 private bool musicOn = true;

 public void Start()
 {
     music = GameObject.FindGameObjectWithTag("Music");
 }

 public void YesButton()
 {
     musicOn = true;
     PlayerPrefs.GetInt("MusicOn", (musicOn ? 1 : 0));
 }

 public void NoButton()
 {
     musicOn = false;
     PlayerPrefs.GetInt("MusicOn", (musicOn ? 1 : 0));
 }

 void Update()
 {
     PlayerPrefs.SetInt("MusicOn", (musicOn ? 1 : 0));

     int value;

     value = musicOn ? 1 : 0;

     if (musicOn)
     {
         value = 1;
         music.SetActive(true);
     } else if (!musicOn)
     {
         value = 0;
         music.SetActive(false);
     }
 }

But it doesn’t work. When I click the "no" button, the music turns off but it turns back on when I go back into the game. How would I fix this problem? Thanks for your help!

New code that mostly works:

public GameObject music;
public bool musicOn = true;

public void Start()
{
    music = GameObject.Find("Music");
    bool musicOn = PlayerPrefs.GetInt("MusicOn", 0) > 0;
    if (musicOn)
        YesButton();
    else
        NoButton();
}

public void YesButton()
{
    music.SetActive(true);
    PlayerPrefs.SetInt("MusicOn", 1);
}

public void NoButton()
{
    music.SetActive(false);
    PlayerPrefs.SetInt("MusicOn", 0);
}

public bool MusicOnBool;
    
// This method will toggle the MusicOnBool and saves it to playerprefs
public void ToggleButton()
{
    MusicOnBool = !MusicOnBool; // sets it to its opposite state
    music.SetActive(MusicOnBool);
    // Below we save the bool (which is either a 1 or 0) to "MusicOn"
    PlayerPrefs.SetInt("MusicOn", MusicOnBool ? 1 : 0); // condition ? true : false, so if the condition is true, itll be 1, otherwise it'll be 0.
    music.SetActive(MusicOnBool);
}

// This method can be called wherever, such as the Start() method in your script and basically it'll load the saved int and check to see if it's 1 which would be true. So if 0, it'll be false, if 1, it'll be true.
public void Load()
{
    MusicOnBool = PlayerPrefs.GetInt("MusicOn", 1) == 1;
    // EX: MusicOnBool = 0 == 1 will result in false
    music.SetActive(MusicOnBool);
}
