Taylor Swift was feeling her big Reputation during her Eras Tour show in Cardiff, Wales, on Tuesday, when she performed not one but two diss tracks from her oeuvre: “I Forgot That You Existed” and “This Is Why We Can’t Have Nice Things.” Eagle-eyed fans were quick to point out that the mashup, which came during the surprise acoustic song set that differs every night of the tour, This was not the first time the 14-time Grammy winner had performed these particular songs during the Eras Tour, though. She previously performed both during other acoustic sets earlier in the tour, although it was the first time they’d been combined together. The set, which always features one performance on guitar and one on piano, is a fan-favorite, as Swift aims to perform a different song (or mashup) for each at every tour date.
