In the latest version for some unexplained reason, you guys took away the functionality where the current Artist and Track title info is populated in the title bar of the app and also when you mouseover the dock icon while Spotify is minimized. I listen constantly at work using my Premium account, and I don't like taking up my screen real estate with the app, even when it's in the background. I enjoyed being able minimize the app and mouseover the icon in the Dock to see what song was playing when it inrigued me. Since I updated to the latest version, that's no longer possible.
