I've heard this for years with the concept that the cat's vocal range developed to be like this. But not once had I ever heard a cat sound anything unlike a cat. Until...my recent adopted fur baby. He freaks me out how much like a kid he sounds. Just the other day, he let out a sound that even my coworkers on a meeting call thought I had a kid. It's a little unsettling at times
Mine has learned exactly what corners to yell into such that their cry/meow echoes and reverberates everywhere so it can't be ignored. It's kind of impressive how smart and adaptable cats are, lol.
I'd be leery of storing the music files in a git repo directly as MP3 tags and metadata are a wild west and some music players do wacky things like update ID3 tags with play counts, etc. on every listen (which would require committing and pushing music on every listen!).
