The Alexa Music Skill API enables devices to understand a user's voice commands to integrate a music service with Alexa, with features like setting music alarms, multi-room music etc. It enables music providers such as Spotify to add their music service to Alexa-powered devices. This allows users access to music from your catalog, and to ingest your music catalog for voice modeling purposes, or to provide metadata for audio playback from your service, and more. Alexa interprets customer input and communicates the input to a skill as a request with a JSON payload containing an Alexa directive.
