Stop music playing after changing scenes.

I have a main menu that plays music and i click on a button that takes to me to a different scene, the music continues to play (Good) but when i go to the main game it continues to play (This is what i want to stop). I have tried many things and the one that i think should work doesn't.

if (Application.loadedLevel == 0)

     {
         DontDestroyOnLoad(transform.gameObject);
     }
     else
         if (Application.loadedLevel == 2)
     {
         Destroy (gameObject);
     }

The script has the code to play the music and that's why i have to don't destroy on load, i thought that if i deleted the object the music would stop. I get no errors in the console it just doesn't work.

Please try and help me.

Thank you for answers
