title: Correct Field Name For "Album Artist" ID3 Tag In SoX With LAME
body: <p>I've got SoX compiled with LAME, and it works fine, I can make an .mp3 file with common ID3 tags.</p>
  
  <p>But I can't figure out what to call the "Album Artist" field so that I can specify a value.
  For example:</p>
  
  <pre><code>sox -n --comment "Title=Sweep" --comment "album_artist=ALBUM ARTIST TEST" input.mp3 synth 3 sine 20-20000
  </code></pre>
  
  <p>Will properly make a file that sounds like a sweeping sine wave, and the ID3 title will be "Sweep".
  But the Album artist field is still blank.  I've tried several variations, to no avail:</p>
  
  <p>band
  bandname
  albumartist
  album_artist
  group
  orchestra
  accompaniment
  soloist
  performer
  leadperformer
  TPE2, which is the technical name in ID3 for the field I'm trying to give a value.</p>
  
  <p>But none of them seem to work.  Does anybody know the right "name" to use for this value?</p>
