I agree the transcription is awful, but would you say it's unrecognisable?
That is to say, I think you don't give people good enough credit if you think a bad transcription will preclude many from being able to recognize something.
Similarly, a novice butchering a song on guitar is likely completely wrong, but people will still recognize it if the general shape of the song is preserved. Heck, most novice guitars probably are not tuned properly.
