She does have some tweets with that the tag/word “Entanglement” in them as shown here, but I’ve personally heard nothing about the song. It looks like it was supposed to be released before “Minds Without Fear” as detailed in the first tweet on that page, “you’ll have 6 songs by end of the year If you get all released. Lifeline, propeller seeds, entanglement, India track + 2 more”. This is probably just a song that she’s been working on slowly over the span of the whole project, or has simply abandoned.

She did say at one point that she’d be half-way done with the album recently after finishing this song, but she has only officially released 5 songs as of yet. So maybe it’s kind of a surprise song! At least I’m hoping so.
