title: read id3 tags from mp3 using javascript
body: <p>I know this has been asked here before but my conditions are a little different. I am making a chrome app so i have access to all the latest JavaScript file apis it supports without worrying about compatibility. More over i would really like to do this my self.. ie without any library. A tutorial or a guide will do. After all how difficult can it really be?</p>
  
  <p>Basically i have mp3's that user adds and i want to be able to read most basic information like artist and Album (actually, just these two but others wont do any harm).</p>
  
  <p>I believe i have the idea of what id3 tag is and how can the info be read. I just have to see it in action just once.
  Thanks</p>
