i dont have a prime account and i can do everything i want. (when uk update comes) you should be able to play any music you would like to upload on to amazon music. i use spotify. tunein. all my lights (hue) work as well as turning off my tv, soundbar PS4 etc (harmony hub)
BONUS FEATURE: i use the 'alexa flip a coin' to decide who makes the tea (the wife always wins.. im sure its cause women stick together)
