After listening to Deliverance for the first time in a long time, I must say that it is hands down Opeth's best song.
They have many songs that aren't far behind, I'm not suggesting that Deliverance is THAT superior, but overall it's just so damn mindblowing.
Don't even get me started on the outro.
It also has the epic "Choking on dicks!"-line, which makes it even better!
