[DespairScent]

1. Load the game with music already muted

2. Enter "Load" or "Co-op" menu.
3. Exit back to the title menu.
4. Now, despite it shoud be muted, you can hear the ambient title track (spring_day_ambient), and by entering "Load" or "Co-op" menu, you can hear another one (title_night). Clicking "mute music" button at this point (switching to "unmute") mutes it.
