Can't wrap my head around why Spotify would remove the ability to add new radio stations on the Radio page (Windows and Android). What used to take two steps (from the logical starting point of the Radio page), now requires you to navigate to the Artist/Album, click on their info for the dropdown, and create a station. Sure, it's not that much more difficult to do, but just makes more sense to me to have the ability to add radio stations directly on the Radio page by searching for Artists/Albums/Songs. I miss my beautiful green button. Just my worthless $0.02.

That's a great idea, but something similar has already been suggested.
