Hi, I'm super late replying to this but I finally decided to make an account here to let you know that it looks like you're missing a demo of Cake that I have so I figured I'd share it here in case anybody else doesn't have it either :3 The mixing on this version is different, they used a different sound for the main piano part and there's an epic guitar solo at the end! This one has been leaked for a while but I see a surprisingly small amount of people talking about it? I personally prefer this version lol.
