I only remember Born This Way getting airplay updates as large as Shake it Off. But I also remember Born This Way having a moderate sized airplay loss once rolling came in.
Lady Gaga's "Born This Way" was released in a manner that made finding the "rolling effect" for either airplay or the download decrease difficult to detect. Gaga released "Born This Way" to radio and to download services on a Thursday, after four days in the tracking period had already passed (pre-streaming era). Because of this, Gaga was ensured an increase in both sales and airplay during week two.
Taylor Swift's "Shake It Off" debuted at # 58 on Billboard's Country Airplay Chart, just in case anyone wanted to know. I'm not sure how the "rolling effect" will affect her at that format.
Her very first day wasn't absolutely huge considering the song debuted at 6pm est. What was her pop update that day? I would say tomorrow she could have a larger roll considering her update was 20 something million AI.
she only had like 800 spins last Monday remember? so if she got played 1200 times like she has been the past couple days, it's gonna appear as a gain of 400 spins. Monday wasn't a full day. Tuesday was the first full day
