I just got overwolf not too long ago, and found Spotify in their appstore. For any one who plays PC games, it is a great way to operate Spotify while you're playing, and it comes with a Teamspeak3 overlay app. Simply a brilliant piece of software. So much so, that I even connected it with my Facebook and Gmail. For the "uberconnected," there are other apps for the other major social media sites and skype calling. To have all this centrally accessible in-game for a quick check or something without having to switch screens, and even putting some stuff on hotkeys (I made spotify [F11]) such a great convenience.
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.
