Cover art for Banshee Beat lyrics by Animal Collective

There is also a sense of carpe diem. Note the atheistic pessimism of the line "So I duck out and go down to find the swimming pool" and the following line "Cause when I'm snuffed out I doubt I'll find a swimming pool."

.... As an atheist, and one who used to wallow in pessimism, i dont see how this is atheistic pessimism. Pessimism, perhaps, but more like depressive realism.
