Stuck

For countless months I've had this piece of classical music stuck in my head  & couldn't work out whether it was from a movie or who it was by.
Today, while listening to Ase's Death on youtube & completely not thinking about the aforementioned melody, I saw a video in the corner that I decided to click and lo and behold, it just turned out to be the song I had been searching for for months.
So, with sweet relief, I present a most joyous stuck in the head.
