Hi What HiFi. I liked your Streaming Services article and have just tried joining Spotify - only to find the mobile app needs a Google Appstore account to download. I have an Amazon account, but so far have (tried to) avoid the Google account spy network. It would have been nice if your article had said which App stores the service was available from... I see Deezer is on Amazon, so I may have to go that way instead.
( Personally, and with extensive IT knowledge, I think we all take far too lightly the plethora of personal data that Google and the likes are gathering about us! )
