You can add Spotify music to the long (and growing longer quickly) list of capabilities for the Amazon Echo. If you are a paying member of Spotify's Premium service, then you can setup Spotify to begin using the Echo's voice commands so you can kick off your favorite tunes. That's the third big music streaming service to add support to the Echo, including Amazon Prime & Pandora.
