I Was Glad by Hubert Parry is one of the dullest, most overrated pieces in all Victorian Choral Music. And as most people with a pulse know, there's no music duller than Victorian Choral Music. It has one compelling chord progression at the beginning (the entrance of the chorus), and another at the end. In between are six minutes of the least memorable and most bombastic counterpoint imaginable. I've probably heard this piece a couple dozen times and I can't remember anything between the beginning and the end.
...but at least Hubert Parry isn't Charles Villiers Stanford.
