Honestly, I do wonder if they originally had a plan for Cruel Summer this summer that was botched by Corona. Album tracks that are pushed around the time of an album release don't often do well as singles unless they're the next one, about to be released. (Thinking back to 1989 where the songs promoted with the album release were Welcome To New York and Out of the Woods...Out of the Woods got a good bit of attention as a promo single around the time of the album release, and didn't do well as an actual single down the line). Maybe they figured if they didn't draw any attention to it or push it to people just yet, it would be fresh enough by the summer to give a strong campaign to. I'm also remembering when the fan met her at the Cats premiere and told her Cruel Summer needed to be a single, and she said "But don't I have to wait until the summer for that?"
