"Anti-Hero" It quickly became Swift's biggest hit ever, reigning atop the Hot 100 for eight weeks and surpassing "Blank Space" as her longest-running No. 1 song. The same week that "Anti-Hero" debuted at No. 1, Swift became the first and only artist in history to occupy the entire top 10 on the Hot 100.

'1989′ Swift's 2014 album, 1989′, stands out as the artist's best-selling album. In total, the album has sold over 14,332,116 copies worldwide.

Some fans have gone even further with a theory called the '112' day rule. Essentially, from the first day of the Eras Tour to the release of Speak Now (Taylor's Version) on July 7, 112 days lapsed. Then, from July 7 to the release of 1989 on October 27 is also 112 days.
