Can it Be - end of Rae's verse on the album version, someone is saying no no don't do that shit or something with gunshots in the background and the demo is missing this. And after Ghost's verse, when the beat changes and changes back to the hook, the album better version plays the entire sample starting with "can it be..." And the demo starts with "all so simple". I used to think Ghost's verse was a different recording but I think it's just the pitch of the crappy quality.

Heaven & Hell - at least one difference is when Rae is taking at the beginning, Blue Raspberry is singing and she's not on the album version. I didn't listen to the rest of the track after that though bc the buzzing was getting on my nerves and I don't recall anything else that was different (that stuff usually sticks out in my mind/nostalgia type shit)
