Started to hear unfammiliar music on PW

So I was just playing on my server.
But all of an sudden an Asian kind of music started playing, it was snare music.
And then I walked in an forrest and all of an sudden I hear this music I never heard in PW but hear in M&B: Warband camplaign.

Why is it playing all off an sudden while it never played before?

Thanks

you are actually going crazy.

A system was added to PW a while ago that selects the type of music to play based on a few things, like whether you are in an area crowded with scene props or open terrain, whether there is a lot of fighting going on nearby or you have just died, near a castle owned by an enemy faction, near your own faction's castle when at war, in the outlaws faction, etc. It is purely client side, so no effect on server performance. The music is all from M&B Native single player, though some of it is rarely played. See script music_set_situation for implementation details.

The Mount and Blade music is very mystical and awesome, its like rainbows in your ears.  Nostalgia for original MB beta when I actually had the music on.
