"This one hit me hard," she wrote. "I’m so in my feelings (more so than usual!) over what you all did here for evermore. Blown away by how much you care, and how long we’ve been caring about each other. Love you, so very much."
Swift included four red heart emojis in her tweet -- which, naturally, had fans putting on their detective hats in the comments. (Is it just a random way to show her love for Swifties, or could it be a hint that the re-recording of Red, her fourth studio album, is near?)
Billboard reported earlier that Evermore’s sales surge was fueled by the set's modern-era record-breaking vinyl LP sales, autographed CDs and discounting on the digital version of the album. Evermore last held the No. 1 spot on the Billboard 200 on the Jan. 16-dated chart.
