Online Zen Music Radio Station?

Ive Been looking for online radio station that plays music similar to the songs heard in movies like "hero" with jet li. its very soothing music. they use a type of japanese violin or guitar. ive have also heard the instrument played in the beginning of house of flying daggers as well as other movies like the last samurai with tom cruise. i tried looking through windows media player radio but cant really pin point the type of genre it is. any help finding an online radio station that plays that kind of music would really help. also if anyone has heard of NPR's echoes that is another genre that i enjoy listening to when trying to work.
