I am not going to comment on the animation, or song in your link. Just the 'voice' which has zero emotional range.

There is an intresting recent study that used really short clips of people laughing and asked: "Are they friends?" This is just laughter and it was played for people around the globe. People did better than random. Not 100% by any means but well past random change for a few seconds of laughter.

Now, extend this emotional void to a full song and it get's down right creepy.

I understand what you are saying. I guess not all of are are affected by this. I guess at this point it's subjective. I understand why you might feel it's creepy.

As for the study, I believe you are referring to this: http://newsroom.ucla.edu/releases/friends-or-not-laughter-re... I have not read the article but I listened to the sound clips. They are definitely different. But I do not associate either with friends or strangers. If it were just these 2 clips I would probably identify them correctly because one is more involved and energetic and I know there is one of each kind. But I would probably find it more difficult to identify the type of each clip from a set without any extra knowledge.
