My "controversial" take is that I don't think loml is mixed muse. I think it is pretty firmly about one person (the rat).
BUT! - I think it is a song, that much like many others on TTPD (and her discography as a whole) can be APPLIED to multiple muses. But Daddy I Love Him I would argue is more blatant in its inspiration, but it also describes a very general experience - disregarding others disapproval over your choice in partner, in Taylor's case, while in the public eye. I think thatβs part of what fuels theories about the end of the song describing her relationship with Travis because you could just as easily apply it to any of her relationships.
The Bolter is also one I find interesting, because a romantic muse just feels so irrelevant. We know Taylor is writing it and we know it's seemingly from her perspective, though perhaps influenced by similar figures throughout history. The descriptions given of romantic interests are simultaneously so vague and so hyperspecific - detailed enough it can easily fit most of her public relationships, not detailed enough you can effectively pin it on one particular person.
