AI-generated anything sends a message of 'I do not care about quality'. You might feel that that's unfair, but it's the impression you're making on a large segment of your potential audience.
As opposed to thinking of a play on words between the game/the original song and having an AI make the joke cover per my directions, instead of me just doing it (worse) by hand, which is "I don't care about quality?"
The whole point of the video is not the visual component, it's really just about sharing the non-AI music.
They read AI as 'grifter who probably doesn't care about any aspect'.
