I got the echo for Christmas and was playing around with it today trying so set an alarm to music. I have amazon music unlimited working 3.99 version. However I'm still on 3 trial. But when I say wake me up to Christmas by wizard or whatever I can't find a song. I tried wake me up to radio 1 and it just turns radio 1 on. I know this is a new feature so maybe there are technical difficulties. Anybody know what I'm doing wrong?
