Most music as long as it isn't life-suckingly boring. The coolest thing I have on my ipod is probably Patti Smith (but I never listen to it) and the naffest thing is prob Christina Aguilera (which I listen to quite a lot) - make of that what you will.
Cry Baby, Blues Brothers, Lilo and Stitch, Endless Summer, Wayne's World, Kung Fu Hustle (juvenile humour basically). Plus all the usuals for an eighties child - Star Wars, Breakfast Club, Wierd Science, Outsiders, Stand by Me, Ferris Bueller's, Goonies, Bill and Ted's....
Holes, A Gathering Light, Lord of the Rings, Harry Potter, His Dark Materials Trilogy, The Princess Bride, War Reporting for Cowards, Hitchikers, Freakonomics...
