# Introduction

If you are building an app or service that interacts with LISTEN.moe chances are you also want to provide with currently playing song information, and the WebSocket is the way to get it.

The WebSocket allows you to establish a connection and wait to be notified of new data in order to avoid spamming the API for updates. This means that whenever a song changes or a music event starts, we will notify you over the WebSocket for you to do with that data as you please.

First head over to the spec to see how the WebSocket works and behaves and then take a code sample from usage or write your own!
