MJ Fans: Has anyone ever noticed that the vocals in "Break of Dawn" are autotuned?

The song technically is not autotuned the only part that sounds autotuned is when he sings break of dawn a couple of times before going back into the next verse. That part of the song really is not truly autotuned its more of a muffled sound in his voice if you listen to songs that are autotuned you should be able to tell that this song did not have autotuning. There are other types of sound distortion that is used rather than autotune. The video below shows what autotuning sounds like, and if in fact he did use autotune it was for an effect not corrective reasons he had no need to correct his voice.
