This is not a duplicate of any idea I have found. My idea was not described as well as I wanted in my previous post. I would like Spotify to show in Fullscreen mode only the song name and artist name without anything else. No album cover. No empty space on left and right margin. Just the text in as large font as humanly possible. This way I can be away from my desktop computer and see the name of the song and the artist. It will not feel like I'm working with my computer when I can be far away from it while listening to music.
Tip for the programmers: you can make a bitmap of the text (screenshot) and enlarge it, if the size of the system font is not big enough for a desktop monitor.
