Anything with a good beat really. I really can't say that I don't like country or rap either. I prefer not to listen to it, but there are a couple songs that belong to said genre's that I do like. If I feel motivated, it's gonna be hard & heavy, or something thudding and repetitive.
In no particular order: Fight Club, Sin City, LotR, 13th Warrior, Matrix, any of Kevin Smith's films, Jackie Chan movies, Pi, Suspect Zero, Seven, Kiss the Girls, Along Came a Spider, Momento, and others I can't think of right now...
House M.D., How I Met Your Mother, Six Feet Under, Robot Chicken, Smallville, some Anime like Cowboy Bebop, Witch Hunter Robin, Full Metal Alchemist, etc.
IThis will be a mix of authors and titles. Plato, Margaret Weis, Tracy Hickman, R.A. Salvatore, Tao of Pooh & Te of Piglet, Kurt Vonnegut, Neitzsche, Epicurus, Anarchist's Cookbook (I browsed through it a couple times).
