YES to the Pablo Neruda love. He's amazing! Addict I am, it continually amazes me when I meet people and they say, "Neruda? Who?" (In case you're wondering, that happened just the other day. I'm still a little irritated.) But, yeah. Despite being what Dean would probably think of as fruity, Neruda's poetry is wonderful for Supernatural. Lots of angst and melancholy and hopeless, desperate, kill-or-be-killed love.
