So I wanted to try making my own custom theme for Opera GX, I've been following the tutorials found online, and it's worked except for 1 problem. When I try to add multiple background musics to the theme, it plays all of them together. I have some experience, but definitely not very sufficient, so I'm hoping someone can help me understand and maybe fix the issue.
So far, I've only changed the background music.
