title: XML format for mp3 files
body: <p>I'm developing a desktop app that will scan a user's system for mp3 files and send their whole collection to a website. I'm assuming the best file format for sending this data to a server would be XML -- although correct me if I'm wrong.</p>
  
  <p>Can someone kindly comment on whether the formatting of the sample XML file below looks okay? Thanks!</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;collection&gt;
      &lt;artist name="Michael Jackson"&gt;
          &lt;track&gt;Beat It&lt;/track&gt;
          &lt;track&gt;Thriller&lt;/track&gt;
      &lt;/artist&gt;
      &lt;artist name="The Beatles"&gt;
          &lt;track&gt;Hey Jude&lt;/track&gt;
          &lt;track&gt;Yellow Submarine&lt;/track&gt;
      &lt;/artist&gt;
      &lt;artist name="Eminem"&gt;
          &lt;track&gt;Lose Yourself&lt;/track&gt;
          &lt;track&gt;Without Me&lt;/track&gt;
      &lt;/artist&gt;
  &lt;/collection&gt;
