In light of the finale, I developed a little theory that Twilight Sparkle was transported to Sori 52 by the Elements of Harmony. There, she met with Celestia, and discovered her true destiny.
In my mind, the album's soundtrack has taken on a different meaning, and become a musical interpretation of what Twilight was thinking, imagining, and experiencing throughout her time there, leading up to her returning to Ponyville as an Alicorn.
The album has that faraway feeling, and takes the listener to a distant and unknown place in space, where the music reflects feelings of amazement, happiness, sorrow for the past, anxiety for the future, and gradually reach inner-peace. To me, this is just what Twilight could've felt while with Princess Celestia, while her thoughts hovered over her friends and what her life has been up until this life-changing moment.
Each track inspired me to write a coherent description of the fragments of thought or long trains of unconscious memories that could've raced through Twilight's mind, eventually reaching the breakthrough that mentally prepares her for her destiny to be realised, and reaffirms just what it is that Twilight was born to do.
