Eh, I don't entirely agree with this. I think the song does a good job at making it fairly ambiguous as to what she's craving. Sure, there are a couple of plain references to wanting someone in the chorus, but around that you also have a longing for home, for the familiar, for the person she thinks she used to be but realises she still is. I think it's more about feeling disorientated in a foreign land and reaching for control and comfort. But then that's just one take; the song offers many. Which is why it remains the best song we've heard so far.Medellin and Crave recapture some of the emotion of yesteryear (which I actually think a lot of those “Leonard” fanatics are alluding to), even though both songs are ...well ...narrated nostalgia. Crave is most certainly about her craving something from her past.
"Medellín" is a little more straight-forward, but it's so joyous and wistful that I just want to take it at face value for the sun drenched daydream it is.
