Musically and lyrically "So It Goes..." (heretofore referred to as "So It Goes") reminds me of "I Don't Wanna live Forever." It's sexually focused, and it's very slick and intentional, verging on dark pop. The song is focused on some new boyfriend (the Internet would have us believe Joe Alwyn) who Swift finds attractive and who she apparently feels deeply connected with. The song itself though may prove to have further surprises.
