I just downloaded the Dish music app to my iPhone to see how it all works. It seems like a really cool feature (although I don't think I would use it very often). But I'm having trouble accessing all of my music. I click on the red square with the music symbol and it takes me to my iTunes music. I can even see all of my playlist. But for some reason much of the music is greyed out and will not let me click on it. I subscribe to Apple Music so it all comes from the same source. Any idea why some of it will play and others won't?
