Anything other than being in class. Sports, movies, and otherwise normal stuff.
Pretty much anything, besides country music (which technically isn't music as much as some asshole whining about his dead dog, pickup truck, or tractor). DMB, Linkin Park, Mudvayne to name a few.
Godfather 1 and 2, Old School, Super Troopers, Goodfellas, Wedding Crashers. It's all deadly...
Sopranos, Entourage, SportsCenter
Reading for fun would be an interesting hobby.
