Spotify mini player Chrome's exntesion, check out the story here
When we are working or just browsing it is inconvenient to have to switch to another window to play/pause or jump to previous tracks or forward to upcoming tracks. Also, we lose focus or get distracted once we navigate away from our current window and open Spotify. With this simple extension we can eliminate the need to navigate away from your current window to control Spotify. This extension has another nifty feature. With a quick right click on the widget, you can search a song by name. So for example if you hear a tune on Youtube you can quickly search it on Spotify without navigating away from your current window. Then you can maybe add it to a playlist later.
