Ambient Music Playing So Rarely

[Shizofrend98HR†]

Often the ambient msic in my game stops playing as regulary as it sohuld. Does anyone kow quick fixes for this or thing gameplay wise to avoid that stop ambient music or may trigger some sort of bugs that keep the msuic form playing? Also for some reason music in east part of map plays lot more often and is louder then in any other part of map and music in heartlands and middle-ish part of map plays extremelly rarely and is pretzty quiet.
