I personally think she looks absolutely yummy in short blonde hair but the dark hair's good too.
I hope we hear something soon... it's so weird to have no info on an album a week before it's release.
@Edge: Yeah, I pretty much second everything identity said. BoA though might not be the best introduction to K-pop as she's a soloist and the girl group craze over there is even worse then in Japan plus she's a bit more pop while other acts tend to be more R&B/hip-hop influenced. I'd also recommend K-pop as long as you're not looking for a lot of diversity and originality and just want fun and catchy songs.
