Maybe the most depressing song ever made...it's so good, though. Whenever I listen it, I have waves of melancholy spilling over me. Even if I'm in a perfectly happy mood, this song will make me reflect on things that could've, should've been so much, it damn straight earns the stamp "depressing song".
But they do it so well...i don't like depressing music, but by the Flying Spaghetti Monster, this is some good music
EDIT:
It can't be a coincidence the following song on the album is "Optimistic", lol. The band needed to stop it's fans from killing themselves.
