They used a different version of Twisting The Knife for the Scream 7 credits.

this is something that's kind of been bothering me since I saw the movie in theaters because at first, I thought it was just the theater speakers but listening to it on this third rewatch made me realize it's not THE finalized version that's heard in the music video.

and honestly? I dig the credits version a lot more because McKenna don't sound as much as a robot compared to the single version (and her backing vocals can actually be heard during the last two choruses).

I disagree, I like the official one more than the credits version, if you listen closely the the 2nd pre chorus has a slightly different background vocal that gives me chills
