Full HQ leaked song of Melanie Martinez's called Rocking Horse that was supposed to be on Crybaby but was scrapped. It's speculated it has ties to another unreleased song called Haunted and a song that made it onto Crybaby called Teddy Bear, but that idea is just rumor and isn't confirmed. Credit to Melanie Martinez for the song, she owns it. Crybaby Da Mel on YouTube is where I found this leak. Check their channel out for the instrumental version as well.
