Lauridsen’s damn 9th chords

I was listening to internet radio in the office this afternoon, and periodically would check the playlist if I heard something interesting — Palestrina’s Tu es Petrus was quite nice. But then they played some Lauridsen, who is identifiable within half a bar. I suppose it’s good to have your own compositional voice, but does it have to be such a repetitive one? I could have sworn I sang this one, but no, it’s a Agnus Dei. Oh well.
