Black Fucking Metal! Those crazy ass fish you find in the deepest, coldest parts of the ocean. Humanity is going to kill all those fish without having any idea of what they could have told us about the history of earth.... Crushing feeble minds is pretty cool too.
Noktu and Neige (two of my biggest influences), H.P Lovecraft (RIP), Helena Bonham Carter, Quorthon (RIP) and Robert Smith.
Always something different. A few good bands in my lists: Profanum, Gorgoroth, Bathory, Mortifera, Mayhem, Pestilential Shadows, Darkthrone, Marduk, Enslaved, Darvulia, Celestia, Mütiilation, Emperor, Dödfödd, Darvulia, Forgotten Tomb, Peste Noire, Stiny Plamenu and Pink Floyd. I basically like all music. Country is a fucking joke, Rap isn't much better and "pop"-anything is gauranteed to be complete shit.
Drug movies, Horror (Unless its lame) and Comedy. Fight Club, Donnie Darko, Spun and Blow are my favorites.
South Park, Family Guy, Wild Boyz, Trailor Park Boys, and documentaries on murders, religion, history, war or addiction.
Anything by H.P. Lovecraft, my all time favorite author. Edgar Allan Poe, Friedrich Nietzsche, Catherine Owen, and whatever books on the occult i can get ahold of. A few random magazines are a good read every now and then.
Jack the Ripper!
