Unreleased gaga songs

Okay so I'm ashamed to say that I don't know many of these. But because ARTPOP 2 was mentioned and people talked about princess die, I just learned that princess die was an ARTPOP 2 song. I thought frankensteined was an AI song on youtube, but apparently gaga mentioned thats her unreleased song. Are the lyrics same? is the AI song on youtube just trying to imitate gagas voice? I know about brooklyn nights and party nauseous. Is ma ma pa pa pa (on youtube its an AI song) an unreleased song?
