World Library Publications now has a blog, run by Jerry Galipeau, the associate publisher, at which they link such "contemporary" Sanctus settings as this one and this one. Oh, the post also links a Youtube of chant, as if to say "whatever floats your boat." And yet, I think most learned musicians in the Catholic world would not say that liturgy can be completely indifferent to the choice between styles. Fortunately, the blog post leaves comments on, so I'll close them here.
Addendum: the blog moderates comments, so yours may or may not appear.
