In the chorus of another Midnights song, “Karma,” Taylor reels off all of the good things in her life that she considers to be a sign of her good karma.
These range from a purring cat to the breeze in her hair, and she then asks the subject of her song: “Karma’s a relaxing thought, aren’t you envious that for you it’s not?”
Despite arguably being a pretty straightforward question, there were a large number of Swifties who admitted to struggling with the meaning behind this lyric, which might stem from a misunderstanding of the term “karma.”
To bring you up to speed, “karma” is the idea that how somebody behaves in their life dictates whether or not they will have good or bad things happen to them. If you do good things, you will have good karma, and if you are bad, then your karma will be bad.
In short, Taylor is suggesting that the person this song is about has done bad things and therefore should be expecting bad karma, unlike her.
With this particular lyric, she is asking the subject if they are jealous that karma is a “relaxing thought” for her because she doesn’t have to worry about it being bad, whereas they do.
