Ultimately, we're making this change because we believe in the future of both platforms, and we want to make sure it can continue to serve the needs of our users now and in the future. With this redesign, we're combining the technical opportunity of a modern and scalable web player together with a cohesive Spotify design and the features that you've all come to expect across the desktop app.
The company describes the move in a post: The update brings a cleaner interface to the desktop and aligns the web and desktop experiences. Spotify announced today that it's rolling out a redesigned experience for desktop and the web. Luckily for Spotify users on PCs, that refresh is finally here. While it's been functional for years, it's due for a refresh. Its dated design and interface have been called clunky.
Spotify has had a desktop app on Windows 10 for quite some time, but it isn't exactly modern.
