"Blah Blah Blah" underperformed, it was a top 10 in the US, top 15 in the US, top 3 in Canada, so that's hardly a flop.
It sold about 1.5 million worldwide and over 1 million in the US, and is still selling. How's that a flop?
Only underperformed.
"Your Love Is My Drug" is radio-friendly, had small, but consistent sales though it wasn't even a single and on top of that it's a fan-favorite.
