The song looks likely to soar in as her second Hot 100 leader next week.
(Because the Radio Songs chart, which powers the airplay component of the Hot 100, follows a Wednesday-Tuesday tracking week, while sales and streaming cover a Monday-Tuesday period, "Shake" debuted on this week's Radio Songs chart at No. 45 with 29 million impressions in its first two days. It was aided by hourly plays on participating Clear Channel and Media Entertainment-owned pop and adult pop radio stations in its first day and a half.)
"Shake" currently ranks at No. 9 on both the building Pop Songs and Adult Pop Songs charts (which run Monday-Sunday). It's on track to make a record-setting start on each list, as no song has ever debuted in the top 10 since the tallies launched in 1992 and 1996, respectively.
