Well, looks like Boa is finally ready to make her big push into the United States. The teaser video for her first American song and video is online. It's called I'll Eat You Up.
Or you can go here for the American version. Or here for the Asian version.
Certainly respect in the American market has been the Holy Grail of the Korean music industry for some time. But with the exception of the reggae singer Skull (and, back in the 1950s and 60s, the Kim Sisters), there has been very little success by Korean pop singers over there.
I cannot claim to understand the tastes and trends of hip young people anywhere in the world, so I will refrain from speculating about how Boa's American promotion will go. But best of luck to her.
