[Animation nerd alert.] Sorry, but this isn't the first animation to incorporate music. The Black Cat is directly inspired by Disney's Skeleton Dance (1929), and even that wasn't the first to incorporate music. Look it up on youtube/wiki.
This is the first use of music in animation? Well that was an interesting bit to see. It took a few seconds to get comfortable with it, but then it was relatively cute.
So cute!!! I love the song and the voices. The animation, though it's weird to this time, it's cute also. Thanks for uploading!!
P.S. People who see weird things on this video, please go to a doctor.
