Already in the Top 15 at Hot AC radio, Taylor Swift's "Shake it Off" is due to achieve the same at pop.

For the first time since its launch, Taylor Swift’s “Shake it Off” did not make a day-to-day position gain on Mediabase’s rolling pop radio airplay chart.

But thanks to another monstrous spin gain Friday, Taylor’s new song is in position to jump into the Top 15 on Sunday’s edition of the chart, which will inform Mediabase’s official weekly rankings.

Between its Monday evening launch and the end of Friday, “Shake it Off” received pop 6,560 spins. Enough to position the song as the format’s 16th-most-songs for the period between Saturday, August 16 and Friday, August 22, the total also puts “Shake it Off” within striking distance of the Top 15.

Jessie J + Ariana Grande + Nicki Minaj’s “Bang Bang,” which currently holds the #15 spot, received 7,011 pop plays between August 16 and 22.

Based on its current rate of growth, “Bang Bang” will likely add 150-200 spins to its weekly total Saturday. Since “Shake it Off” could add up to 1,000 spins to its total (it has scored at least 1,000 spins each day this week and added 1,266 on Friday), it will no trouble charging past “Bang Bang” in time for Mediabase’s official update on Sunday.

If it has a particularly strong Saturday, it could even claim the #14 position. Currently adding to its weekly total at a rate of less than one hundred spins per day, Iggy Azalea’s “Black Widow (featuring Rita Ora)” holds the #14 spot thanks to a count of 7,702 spins between August 16 and 22.

Also a hit at the hot adult contemporary format, “Shake it Off” is already up to #14 on Mediabase’s rolling chart for that format. The song has earned 2,367 Hot AC spins since launching this week.

If it maintains its rate of growth Saturday, it should receive enough spins to rank as the #12 song on the official Hot AC chart that Mediabase will publish Sunday evening.

— Billboard, which bases its airplay chart on audience, paints an even more favorable picture of the Swift song. Based on building data, “Shake it Off” is poised to reach the Top 10 on the Billboard Pop Songs and Adult Pop Songs airplay charts.
