The other certifications from last month include Gold levels (100,000) for Kelly Clarkson's "My Life Would Suck Without You", One Direction's "One Thing", and Taylor's "I Knew You Were Trouble.
Taylor is massive in Japan. They REALLY love WANEGBT! It's currently #59 on Japanese iTunes after almost 3 years, and she has just sold out 2 Tokyo Dome dates, which is 110k tickets. There would be a riot if she didn't perform WANEGBT during her shows there!
