FYI the mp3's that are downloaded are wrapped with Mp3Wrap. In order to see proper tags and album art you need to use a tool to unwrap it. It is fairly technical, but first you install mp3splt from http://mp3splt.sourceforge.net/mp3splt_page/home.php. Then run the command mp3splt -w MP3_FILE.
Hope that helps
Here is the promised link. You have both my versions of Character Sheet and Non-Player Character Sheet.
About the Character Sheet: please pay attention when adding items with Cover/Front Cover as the math behind is a bit buggy and I am working on a fix.
