[EvergreenFir] is correct: the song referenced by the Daniel's Twitter confirmation is, indeed, [B.B.B.F.F.|"B.B.B.F.F."], NOT this song, "This Day Aria." Following the link included in in the Twitter will take you to the Reddit feed. At the top user Kwulhu's original analysis is the link to the video he's referring to: "B.B.B.F.F."

As he points out, Twilight begins singing in the key of D-flat major, same as "Winter Wrap Up." Thus the tonic, or "root," tone is Db Major (M). Usually, an authentic, "circle," or "complete" cadence will start at the tonic (I) tonal degree (google scale degrees to find out what the roman numerals mean, as it would take way to long to explain it, here), move up to the subdominant (IV) degree, then the dominant (V) degree, before resolving back to the original tonic (I) tone. Thus, the chord progression is I – IV – V – I, thus "completing the circle," or "closing the loop." This progression is very popular for pop music, creating the "bubblegum" Disney-type tween sound. So: Db M (I) –Gb M (IV) –Ab M (V) – Db M (I).

Again, this is apparent in the "B.B.B.F.F." chorus:

I –Db Maj: My big brother,

IV –Gb Maj: best friends forever!

V –Ab Maj: Like two peas in a pod,

I –Db Maj: we did everything together

This is the authentic, "circle," or "complete" cadence. The stanza ends on the tone you'd expect it to (the origin tone), thus closing the musical phrase with finality.

However, during the last stanza, Twilight sings this:

I –Db Maj: And though he's, oh, so far away

IV –Gb Maj: I hoped that he would stay

V –Ab Maj: My big brother best friend

vi – Bb Maj: Forever ...

vi – Bb Maj: Forever ...

Notice something different, there? Yes! The last two Forever's are sung as the submediant (vi — mind the lower-case, there) of the tonic (I) tone! This is a deceptive, or "interrupted" cadence; it feels unresolved because the final tone does not echo the originating tone!
