I mean I like the title's refrences to both royalty and family, given that TFJ's core themes are exactly about her analyzing fame and how she feels due to her dad and stuff. But my main point in saying that it's flimsy is that you have to do a bit of digging to realize that is the title's tie to the record and it's not that different from L+F. I've seen enough album reactions to notice that most people have no idea what it is called that and don't pick up on the central themes of the album (most think some of the tracks are about romance).
I totally get some of the criticims of L+F, but I try to push back on the idea that it was a complete flip in Marina's career. L+F as a title and era-concept had as much thought as TFJ and others, so I don't agree with conceptions that it was just randomly put together with a bunch of filler tracks when the album creation was the same as her other works. It's fine to say you don't like the central idea of separating the tracks how she did, but that's just not how most people frame their opinions and that's what I was trying to point to. Hope I am making some sense
