Music Plays Over Itself

Hello. I am trying to add background music to my game. I have successfully been able to import the music and keep it playing throughout different scenes. However, when I go back to the first scene in which it plays, the music starts again, while the original is still playing. I would like to know how to get rid of this.

Also, I would like to know a way to make the music stop when I enter a certain scene during gameplay.

Thanks!

Maybe you wanna use AudioSource.Stop(); or AudioSource.Pause();
