I think the first album I bought with my own money was Avril Lavigne (SHUT UP! I was only, like, twelve...)
Nostalgic movies that I liked when I was a kid, only to be told that they were considered bad when I was older. But I still like them anyway. These include: The Beach, Hollow Man, The Craft, Halloween H20 (saw it before I saw the original Halloween, when I was ten).
I downloaded Bring It On because I never saw it as a little girl. And I liked it. I might watch it again. It's still on my computer.
For that matter, so is all of Power Rangers In Space. I watched every single episode, non-stop, in order, and I think it's pure awesomeness. Have I mentioned I'm nearly twenty?
...Also, worst of all...I turned in Tali's father and got her exiled from the Migrant Fleet once. <_<
