+Boolean, defaults to false. If set to true, MP3::Find::Filesystem will
+use L<MP3::Tag> to get the ID3v2 tag for each file. You can then search
+for files by their ID3v2 data, using the four-character frame names. 
+This isn't very useful if you are just search by artist or title, but if,
+for example, you have made use of the C<TOPE> ("Orignal Performer") frame,
+you could search for all the cover songs in your collection:
+
+    $finder->find_mp3s(query => { tope => '.' });
+
+As with the basic query keys, ID3v2 query keys are converted to uppercase
+internally.
