I understand, and I had read the tutorial and documentation about Music and had tried many ways to let it check if the music has stopped, and if the music stopped, play the next music. Nothing seems to work. I guess the problem is that I only let it check once, but I could not figure out the way to let it check in each frame, even after I read through the documentation about Music and SoundSource. That's why I need at least a hint, like what function or anything else should I use to let it check in every frame.
