Watched Twice Upon A Time, and noticed the song Doomsday

I finally finished the Capaldi Era and my heart skipped a beat when I heard a slower version of Doomsday called "I'm afraid" play when the Doctors discussed not wanting to regenerate.

Apparently, according to some comments I read, there's also a lot of other leitmotifs during his regeneration scene, which is lovely.

Such a good end to the series, excellently done.
