Calm Radio has nice content but it is like the Hotel California: You can enter anytime you want, but you can never leave! Not even for a pause. They appear to purposely and cynically set up a Help labrinth between Google, Google Play and your payer that is extremely difficult to understand and navigate (if you have bad eyes it's even worse), all designed to block your exit. Their "Help" algorithm which is their Quick Sand. Ironically, all of this sets one's nerves on edge.
