That's super curious. No offense, the noise didn't make it sound more amateurish to me personally, so I wouldn't go as far as to immediately conclude that this was intentional by TikTok, let alone that it is because it didn't like the lyrics, but I'm very curious what is it anyway.

Reminds me of how someone lately was going crazy about weird video-artifacts on Youtube. It was fixed (for his videos) after contacting somebody on the technical side of Youtube, but there was never an explanation AFAIK of what actually went wrong, so I was left pondering if that could be a result of some more ambitious ML-experiments in attempt to improve compression rates or something, but never found out conclusively.
