<h2>--- NOTE: BUGGY? ---</h2>
<p>TODO: Investigate holes in ID3 parsing - for some reason, Album will be populated with Date if empty and date is provided. (?)
ID3V1 seem to parse OK, but &quot;holes&quot; / blanks in ID3V2 data seem to get messed up (eg. missing album gets filled with date.)
iTunes issues: onID3 was not called with a test MP3 encoded with iTunes 7.01, and what appeared to be valid ID3V2 data.
May be related to thumbnails for album art included in MP3 file by iTunes. See <a href="http://mabblog.com/blog/?p=33">http://mabblog.com/blog/?p=33</a></p>
