^Don't forget, though, that the Christmas sales streak started at the last half of the week. We could or couldn't end up breaking last year's numbers. It all comes down to how many people decided to start spending on Christmas Day. Last year is started on the very last day of the tracking, so the whole next week had Christmas sales to bounce off from. However, I do expect the #1 song to at least do 390k-430k. (Which will probably be Just Dance.)
