Well you should know that this album is called Post Traumatic but not only Traumatic. CAL is a real line in this album.The songs before it are exceedingly sorrowful but after it are full of sunshine and hope. It seems that you don't like those hopeful songs but only wanna drown in grief, which was we not really need. You should try to understand this whole greatest album.
(Prove you Wrong: 4,5/10, see the problems I have with Ghosts (and Welcome) but worse; WTWM 7,5/10 very NIN, moody and dark).
