Well I finally understood what the rolling effect is . And it totally explains Applause's and Judas' underperformance .So. because Born this Way ( 1st single ) was veryy big in the beginning , the rolling effect caused Applause to do poorly on the charts ? + Let's not forget Pokerface ( 2nd single) was a mega smash , so the rolling effect made Judas flop. Am I right ?
"This is what she was born to do and she’s loved it since she was a kid. She never takes it for granted. She appreciates every second of it. It’s like she’s painting a piece of art. Until the last color is on the canvas, she’s not done. Until it’s dry and it’s amazing and it’s finished and it’s up hanging on the wall, she’s not done.” - Angela Beyincé (on Beyoncé Knowles)
