Eclectic selection--ranging from Volkslieder to Lieder and modern pop music--with good accompanying materials. Includes song texts (unfortunately no audio files), vocabulary (including links to off-site dictionaries), questions, grammar exercises (although not necessarily integrated with specific texts), and external links (more info on the artists, other grammar sites, etc.). The grammar part is an overview of the basics in English (however, some explanations may be too technical for the occasional, average user). Users will profit not only from having texts available but from the added materials.
Straightforward, although inconsistent presentation (too many different backgrounds for my taste) should not pose major problems for visitors. No fancy, useless interface. Some of the grammar tables would benefit from a review of the underlying HTML (to fill all fields), and all text does not have to be centered... (left aligned makes reading easier).
