While "ME!" was certainly fun and light, Swift added that the single doesn't necessarily "sum up what the album is" as a whole. In fact, she teased that fans can expect a lot more emotional tracks with "in-depth lyrics." "The album has lots of different emotional tones to it, in the same way that a person is never going to just be happy all the time," Swift said. "When I make an album, it's never just going to be a happy album."
