That Music Station performance in Japan is big promo. When she performed on a regular episode back in April 2010, it did wonders.
The Fame Monster:
04/13/10 - 6,803
04/20/10 - 21,536 (performance aired)
04/27/10 - 25,547
This was when it was already months into its run, and that was just a regular episode, not the year-end special (which she's performing on).
