Taylor Swift’s ‘Shake It Off’ Explodes On Hot 100, Becomes Year’s Top Debut

Taylor Swift has not only the number one charting single in the country, but the year's top debut for a female artist.

"Shake It Off," the award-winning talent's new single, just debuted atop the Billboard Hot 100 with 544,000 copies sold.

"The sum marks the greatest weekly total this year and the fourth-best bow all-time, two of which now belong to Swift. Flo Rida's "Right Round" began with 636,000 (Feb. 28, 2009), followed by Swift's "Together" (623,000, Sept. 1, 2012). Katy Perry's "Roar" ranks third with 557,000 sold in its first week (Aug. 31, 2013)," reports Billboard. "Previously, Pharrell Williams held this year's best sales mark, when "Happy" sold 490,000 (March 22). The prior top debut of 2014: Ariana Grande's "Problem," featuring Iggy Azalea, which opened with 438,000 (May 17)."

As previously reported, "Shake It Off" leads Swift's forthcoming studio album. Titled "1989" the album is due for release October 27 via Big Machine Records.

Swift may see strong numbers on next week's Hot 100 as well thanks to a performance at the MTV Video Music Awards Sunday night.
