My best friend and I don't like any of the same things?

To be honest, I'm not sure why we actually get along, but we do. The problem is, we're running out of things to talk about. I've tried out some of the things she's interested in. Like, I'll give the things she likes a try, but if I have to listen to one more Insane Clown Posse song or watch another moronic chick flick, I'm gonna snap. And she won't even give my interests a chance. I've invited her to watch glee or star wars with me and I've offered to lend her a My Chemical Romance CD, but she refuses everytime and even gets mad at me when I try to share my interests with her. Like, I won't even do anything, I just open up my laptop and she'll start flipping out about my "A Very Potter Musical" Wallpaper. I'm the type of person who likes to find new interests and won't knock it til I try it, but we just don't have very much in common...besides Bon Jovi. I mean, I know it's good to be differant, but I feel like there's just nothing to talk about now. We spend most of our time hanging out, on facebook (which I find extremely boring and pointless the majority of the time. I'll log on to check my notifications, but that only takes a few minutes), walking around the neighbourhood to see who we bump into (usually middle schoolers who try to hit on us), or even sometimes she talks on the phone to her boyfriend while I sit there blasting Flyleaf and reading whatever I found at the library that week. What do you think we should do? I've given the things she likes a chance and I don't like most of them. She won't even give mine a chance. Help!!!
