I go to Browse Music, select My Amazon Music, pick Artist, then a song. At the top I see a shuffle symbol. I click on and see a few blue dots moving then nothing. I go back to the Music & Books screen and that song is at the head of the Recently Played list, showing that it is playing. I walk around the house to my 5 Echos and hear that it is playing on the one in the front porch. How did it choose that Echo to play on? Also, when I click on the song in Recently Playing, at the bottom I see a drop down of Now Playing and that shows several different songs on different Echos. In fact when I click on these other Echos, each plays that different song! So I am streaming 3 different songs - I thought you were only allowed one! I'm confused. I want to simply be at a given Echo and then pick a song to be able to play through that.
