"Inevitabilis" from Puella Magi Magica Madoka

A very simple piece of music but very pretty. It was written by Yuki Kajiura. I like a lot of her work. I have never seen the anime that this is from, I stumbled on this music during one my anime/video game music listening adventures. Also, if you're wondering why it's dark it's because I forgot to turn on the lights before I started recording :) Enjoy!
