I often wonder what kind of work actually happens at Spotify. Pretty much every major change to the software or api since I started using it has made the product worse. Breaking libspotify, pointless UI redesigns, obvious, user-facing bugs that go unfixed for years. Removing features like play queue for long periods. There's metadata errors and even audio corruption in some albums that I actually reported to them yea…
Plus internal tools will probably be a major thing too.
