title: Setting "Album Artist" using eyed3?
body: <p>I'm trying to use eyed3, as a Python library, in order to change the artist name for a large collection of .MP3 files.  I tried using the sample code of the project's web page (<a href="http://eyed3.nicfit.net/" rel="noreferrer">http://eyed3.nicfit.net/</a>) and setsaudiofile.tag.artist changes the "Contributing Artist".  According to the docs (at <a href="http://eyed3.nicfit.net/api/eyed3.html" rel="noreferrer">http://eyed3.nicfit.net/api/eyed3.html</a>) there are no other artist fields for a tag object.</p>
  
  <p>Is is possible to use eyed3 to actually change the Album Artist? If so, can you provide clear, concise Python code that does so?</p>
