Interesting to see that people find games more immersive with the music off. Music always heightens the mood for me, thus heightening how drawn into the experience I can become.
The exploring music is wonderful. What ruins it for me is when the game abruptly cuts off the exploring music and begins playing battle music. I dislike this for two reasons.
1. I am sensitive to music. I have actually stopped playing on a few occasions so I could listen to the exploring music. To me, turning off a piece of music before it has finished is like stopping a film in the middle of a scene or yanking a book out of my hands while I'm reading. It is
very annoying to me. It's purpose is to break the mood ("it's time for battle!") It does that. And I dislike it.
2. In my opinion battle music is cheating. When battle music comes on I, the player, am being informed that an enemy is about to attack my character before my character could have any knowledge of this event. The game also thinks it's important for me to know when NPCs and monsters are fighting
each other in the vicinity of my character. I do not need to know any of this.
Better to listen to the wonderful sounds effects the game comes with. Now
that is immersive.
