Other people on discord have the same problem, so it's not really a system problem

### Additional context

_No response_

Look for UI code related to the song selection slider, likely in a file handling the game's menu or song list. The bug appeared after a specific update, so check recent changes to UI visibility logic. Test by running the game with a single song to see the slider persist, then modify the condition that hides it when only one song is present.
