What happens when you play Silent Hill 1 for PS1 on a CD player?

When you play Silent Hill 1 for PS1 on a CD player, it will not function as a typical game because the disc is designed for the PlayStation console, which requires a specific format and data structure. Instead, the CD player will likely read the disc as an audio CD and may only play the game's soundtrack tracks. This will result in listening to the eerie and atmospheric music and sound effects from the game without any gameplay or interactive elements.
