"The Poet and the Pendulum". This is the song that practically saved the songwriter from committing suicide, since the song is about him. The weird screeching noise followed by what sounds like a snapping chain midway through the song. Selected lyrics include:
"Iím afraid. I'm so afraid. Being raped again and again and again."
"You live long enough to hear the sound of guns / Long enough to find yourself screaming every night / long enough to see your friends betray you."
"Cut in half - infanticide."
Their latest album, Imaginaerum, gives us such creepy gems as "Ghost River" ("He will go down he will drown drown, deeper down..."), "Song of Myself", and the aptly-named "Scaretale".
