I have always found nursery rhymes to be a little creepy. Some have of the rhymes even have some pretty dark lyrics.
I was looking for some creepy nursery music to be used for my Zombie Nursery display for my Halloween party. I came upon "In A World's - Haunted Nursery Rhymes". It's delightfully eerie with children chanting the familiar childhood rhymes with ominous music and laughter.
I can only seem to find it available in MP3 format, but it's definitely worth a download if you are looking for some haunting nursery music for your Halloween party or display!
You can purchase the download on Amazon here - Haunted Nursery Rhymes
Or you can also listen to it on Spotify
