My doctor turned me on to this app during a recent visit to his office for an unrelated issue. When our conversation revealed I play sax in a few local swing bands and one quartet, and that he plays piano in his church, he asked if I knew about JazzBird, which I didn't. He pulled out his iPhone and demonstrated how JazzBird provided a treasure trove of jazz from around the world with the easiest user interface. In its simplicity it is so elegant. You find a station that is live, click on it, and listen.
not functional (no sound) app fails to play any stations on my freshly updated (marshmallow) LG nexus 5... :-(
