title: How can I get information about Spotify audio stream
body: <p>I want to get information (most important the currently buffered time) about the currently playing music in the Spotify web player.<br>
  I can't find any <code>&lt;audio&gt;</code> tag in the HTML and through the Spotify Web API, the required information can't be obtained. </p>
  
  <p>Is there any option to access information like the buffer, as it could be done with an <code>&lt;audio&gt;</code> tag?</p>
