title: Implement Google-Play-Music like animation (3 bar spectrum beside playlist item)
body: <p>I want to implement something like this. So that I can have control over its color, number of bars, speed, etc.</p>
  
  <p>Below is the animation that is shown next to the item that is currently playing in the Google-Play-Music app.</p>
  
  <p>I will play this in a similar manner: next to the currently playing song in a music app.</p>
