SpotSync
How it works:
The interface is connected to the server through a websocket. After you granted spotsync acces to your account it will look +- every 2 seconds if you're playing a song. If so, it looks if anyone is listing along and sync the time & song. It also sends a websocket update to every connected websocket.
