If you desperately want Spotify in Alexa(Echo), Go to Amazon.com (use Amazon.in login)>Manage Content and Devices> Change Country> US and enter a random US address. Then you can use Spotify in Echo(Alexa, Play my playlist *Your_Playlist_Name* from Spotify)... Remember to set Language to "English (India)" in Alexa app or else you need to speak in American Accent. 😂😂 Have fun ❤️
Actually Amazon music is cheap and has integrated support for echo. Only better thing on spotify is interface and playlists. I shifted to Amazon music because of it's integration in echo family of devices. It's almkst seamless to play a song on echo.
