As for the interpreter of the song, I am not familiar with Oratorio and her works and I couldn't find any further information about her. But her choir-like vocals really emphasize the anime's religious undertones. And I thought it was interesting to note that her artist name is a word commonly referred to a large musical composition for an orchestra or choir.In terms of style, another opening with a similar style would be Eden of the East, so it's not exactly a style I could call original. Nevertheless, "God only knows" along with the animation, results in a highly imaginative introduction that just oozes creativity. And in commemoration of the its third season, I decided to make the single that started it all play tribute to one of the best things ever born in this crappy game of a world.
