Part of the issue is that the desktop app is going to be based on the web player codebase, something that will bring many benefits, but for now (and the future?) many existing and beloved features are missing.
The interesting thing here is that Spotify felt it needed to make a statement such as this one:
“We believe in the future of the Desktop platform and want to make sure it can still serve the needs of our users now and into the future.”
Odd to watch desktop apps becoming a legacy distraction for music streaming services…
Update April 4th:
By pure chance, I created a new Spotify account for myself within the family account (my main account has been compromised by the kids playing with Alexa and I wanted to explore a bit the updated iOS app and its fantastic listening history implementation) and to my surprise encountered the desktop app completely updated (while logged in with my original account the app did not presented itself updated – weird.) Now I have played a bit with the updated desktop app I can say it really seems a great step forward, with a much fresher look and feel. Apple again has a lot of catch up to do.
By the way, the Spotify community blog post promised that “for those of you interested in the technical details, a blog post on the engineering blog is coming soon”. This will be interesting.
