no problem

I don't think there will be a boost, but who knows, T-ara JUST started their promotions for roly poly in Japan so I think that could mean steady sales.
They've already tied Yayaya's weekly sales in 3 days which is pretty impressive
EDIT: T-ara is down to number 5 >.<
on happier notes they won artist of the year at billboard japan awards!
