title: What's this "Album artist" tag iTunes uses? Any way to set it using java?
body: <p>iTunes uses an <a href="http://en.wikipedia.org/wiki/ID3" rel="noreferrer">ID3</a> tag called <em>"Album Artist"</em>, and for one album to be actually grouped as an album in iTunes, both the Album Name and Album Artist must be the same.</p>
  
  <p>As far as I'm concerned, Album Artist isn't an official <a href="http://en.wikipedia.org/wiki/ID3" rel="noreferrer">ID3</a> tag, and from the <a href="http://en.wikipedia.org/wiki/ID3" rel="noreferrer">ID3</a> libraries I've seen so far, none supported "Album Artist".</p>

  <p>Does anyone know more about this strange tag, and how to set it in java (or with any command line utility).</p>
