Stuff. But a LOT of stuff.
Lemmy Caution.
Pain (the punk band, not the goth one), Metric, The Weakerthans, Screeching Weasel, Beirut, The Go! Team, Stars, Mastodon, Joanna Newsom, M.I.A., Mike Doughty, a lot of ska, a lot of pop punk, a l'il bit of metal, all the obvious stuff (ie. the Beatles, Black Sabbath), none of the obvious stuff (ie. Led Zepplin, Rolling Stones)
I like a lot of stuff that comes in trilogies.
All sorts of lawyer shows, doctor shows, detective shows, the X-Files, ST: TNG, Firefly, Simpsons, Futurama, Firefly, Boy Meets World, Transformers, Justice League Unlimited (and any other Bruce Timm based cartoons), Quantum Leap, and whatever else is awesome
The Teacher From The Black Lagoon, almost anything by Chuck Klosterman, Teenagers From Mars, Naked, Stranger in a Strange Land, Namedropper, World War Z, Eats Shoot And Leaves, High Fidelity, I'll think of some more later
My baby brother. Let's face it: he's just better than you are.
