BGM scene issue

Hi! Everyone.
I don't know about BGM.
I'd like to sound Loop BGM in all of the scene.
For example construction.

 Title - GameLevel - GameOver - Title

So, I try to make loop bgm block in only title scene,
But it doesn't work.
Double BGM sound in title scene. It is strange.

What should I do?
Thank you.

I'm not sure I understand your question fully, but to loop a sound every time you go to a scene, you could use this (see attached) to prevent it doubleing up. If you want a sound to loop across scenes, you could use a boolean game attribute with an initial value of 'Yes' (see 2nd attached).

*edit, updated the 2nd screenshot. it should allow for indefinite looping across scenes.

Hi! Rexasul! THANK YOU!!
I could by the 2nd screenshot!
I succeeded! Thank you very much!
