I like to listen to Spotify as I work on my computer. I have yet to discover how to minimize Spotify enough so it can sit on a small corner of my screen so that when I hear a specific piece of music that I'd like to know the artist or title of, I can quickly glance over and get on with my work. FocusBooster, built on Adobe AIR, works this way.
Please bear in mind that the Community is not an official Spotify support service. It's a place where we all help each other, whether we work for Spotify or not. So please use your discretion when using the forum.
