I tried using the sleep[] code, but I found that when I wanted to play these music tracks, the other buttons on my screen became unclickable. I need players to be able to click them while listening to the music, so I tried using random, but it causes random playback from the music list. I'm trying to find a code that can control the sequential playback of music without affecting the screen content, but unfortunately I haven't found it. Maybe I need help again.（PS：Due to network issues, I wasn't sure if that message went through, so I sent it again 😌）
If you want background music playing while a deck remains interactive, you will definitely need a more complicated approach than sleep[]; the discussion in this thread has some examples that may do what you need.
