Finally, there's another reference to "Karma" on Swift's latest album, "evermore." In "willow," the first single from the album, Swift sings, "I come back stronger than a '90s trend." This line, a bit gimmicky, has always stood out to me compared to the rest of the more poetic lyrics in the song. Now fans are connecting it to "Karma," which is theorised to be a '90s rock-inspired album. In the "willow" music video, Swift looks knowingly at the camera while she sings this line, opening up a trap door.
By the time Swift released "evermore," she had gotten involved in another feud with Scooter Braun over the ownership of her masters, which resulted in her plan to rerecord her earlier albums so that she could own her music once and for all. At this point, Swift knew she would be going back through her discography and releasing never-before-heard songs. If this line actually does reference "Karma," she's telling us that it's coming back stronger than ever.
