A:Answer Once Alexa is plugged in, you will need to have the Alexa App on your smart phone to begin the setup process. The device needs to connect with your WiFi signal most importantly. The music can then be summoned by voice if you have a music service on your phone for it to use. So, for example, you can download the free music service Pandora and ask it to play a genre of music, or play songs by artist. You can also use Apple Music, Amazon, Spotify, Tidal, etc, to call on your favorite music service.
