Well...I am not much for her type of music. It's just not what I get into.
For me, it's like she just popped up out of nowhere and it's strange. She was just *poof* there.
As far the dress, quirkiness, etc....I'll be honest. I feel like it's just a vehicle for her to get as much attention as possible. But you have to remember, I grew up in the heyday of Bowie, T-Rex, Queen...real glam, the birth of glam. So for me, it seems as though she's just out there trying to outdo what's already been done before her. Which, in my opinion, just isn't going to happen.
But that's just my take on her.
