Amazon launched music streaming service in the UK yesterday. It is free to Prime customers like me, so I tried it our last night on the web and the iPAD app. It's OK. I suppose all these Spotify rivals are all pretty much of a muchness. That said, the lack of adverts is a big plus.
I was surprised to find I couldn't seem to access it on the Amazon Fire Stick. Checking the interwebs today suggested that I should. Maybe I am just too dim. I will look again later.
As a vaguely related Amazon aside I have got Miracast working via the Fire Stick to use my TV as an extra Windows 8.1 monitor, but the latency seems to make the mouse unworkable. Chalk more noodling around with little to show for it up to experience.
