The Crooked Man. It's not really a song but a nursery rhyme which was played in the movie The Conjuring 2. It's stuck in my head at the moment. I don't know who wrote it, I googled it and it only 说 it was written 由 England.
I can't find the original version which is with heavy 音乐 in it but Taylor Swifts "I Know Places" and "Clean" from 1989 is totally into my mind, I know it's kinda old song but I 爱情 it's lyrics and I feel the song is itself sensational.
