She should be safe to be above Super Bass on the Hot 100 this week. Super Bass is behind her enough on airplay, & digitally they're almost neck-in-neck; plus GaGa was actually ahead digitally in the beginning of the week.
I have to look at sales estimates for The Lazy Song (provided by Kworb), because I think she has a far shot of jumping over The Lazy Song on the Hot 100.
