I cropped your image to make it easier to see when using with a phone:

Thanks @Deceit - I put down a screenshot of the map.

I appreciate the link. I had less trouble figuring out how to play the music and more trouble figuring out where the map was pointing. A hint for anyone struggling: zoom out the world map more and it should be easier to identify the lake drawn on the map.
