As far as I've been able to tell, his albums all tell a story, from start to finish. This song is NOT meant to be a single. This is like, what if Dr John was leaked before we'd heard anything else? It would be just as polarizing. We're not getting context here, even though it's a good song, and has a gorgeous short film to go with it.
I rather like it, even with its' differences from what he's done in the past.
