It wouldn't surprise me in the least if #Beautiful made it onto the album. Personally, I'd rather it not. By that time we would have already had the song for a year and it would feel like a random old song thrown into the mix (ie. Radar). I'd rather it just be a digital bonus or deluxe track.
The Art of Letting Go just HAS to be on the album. It's so beautiful and tragically underrated. Mariah said it was the first look into her new album, so it's safe to assume that it'll flow well with the rest. It would make for a flawless second track that turns into an interlude that leads into a banging finale.
I forgot who it was, but someone mentioned in base last week that Triumphant could be cut down and mixed into an interlude. Personally, I love that idea and think it could work well.

Almost Home won't be on the album.
