The only solution I have found to this, is that it actually only plays the generic libraries or generic artists when spotify is set as your default music library, so e.g. I can say play Kasabian, and it will play on shuffle all there songs easily from spotify, I can say from the genres and moods tab on spotify play 'Chill' and it will play it easily. I presume that Spotify have not enabled custom playlists to be played and therefore this is the only features and there is some misunderstanding here, until Spotify properly clarify it though that's the best solution I have come up with and I have had mine a few weeks now. Also tip if you are british and you want to change your wake word to computer, pronounce it as 'combuder' and it works every time, lol.
I don't know if there was an update or if it's solved now but I'm just a new user and for me it works like this "Alexa, play the playlist 'amazon' from Spotify" the amazon between ' ' is my playlist's name
I'm having the same problem as some others, I am in the UK so wonder if it is a UK restriction. I have tried renaming playlists, its my default music service and tried re-connecting everything. I can only find generic playlists of ones created by Spotify i.e. discover weekly.
Would love to hear is anyone in the UK with a UK Alexa account has this working?
As I've said several times before, you need to have a paid - for Spotify account. Create your playlists, then tell Alexa 'Alexa, play playlist '. You can then tell her to skip track, pause, resume etc. Geoff.
