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 ?
