New source for classical music lyrics

[stormwatch]

http://www.recmusic.org/lieder/ seems to be the most comprehensive archive of classical lyrics. Is there any chance to include it in the lyrics plugin? I've already emailed the site admin for permission but she didn't reply yet. I've also suggested her this would be much easier to implement if the website could accept urls of the form, say like:

http://www.recmusic.org/lieder/?q=%s&textonly=t

(with %s being actually the string submitted for the query)

or similar (for example .../?author=Schubert&title=Der%20Leiermann&results=1), in order to retrieve *only* the full song text in the original language (including line breaks and possibly italics, bold, etc). This would mean also less data to transfer hence, less server load.

Even if she doesn't change the url format, is it possible to use that lyrics source as it is now with the lyrics plugin?
