hard to say "what" her music is. watched a special about her and they went over how the original plan was to make it as a "Tiffany type" pop-star. When that never made it big, they reinvented her as this "dark" chick.
No, but she's 'gay friendly'
She's been reportedly been involved with both men and women and has no preference.
Well, that's what people who are close to her say.
I thought she's married.
Big fan of her stuff, especially "Jagged Little Pill"
If you had to put a label on her style of music, I would say post grunge/alternative
