There is a way:
1. Enable console command with UnRen.bat (can't link to download, itchi don't let me)
2. Use this command when the music is playing:
renpy.music.get_playing(channel='music')
3. The name of the file will appear, you can go to the music folder to play or check on the document "music index" on the main folder of the game to know the name.
