I think you are misunderstanding something. And also assuming a lot more is going on than it actually is.

First of all, the songs are the main part. All of the rest is just secondary. You can not talk about anything related to Vocaloids without talking about the voice synthesis software, the voice banks and the songs using them.

Secondly, most animations that may or may not accompany songs are little more than slide shows with moving elements on the screen. Many songs don't even have that. Many only have a picture.

Thirdly, out of the songs that become very popular, some get fan made choreographies. In this process, motion capture using a Kinekt helps a lot, but you need to do fine tuning for a smooth result.

Each of these steps is within the realm of what a single very dedicated person can do.

Also, there is no such thing "the voice is synthesized from several people and effects" . Each voice bank has a single donor. And you can purchase the Vocaloid software and voice banks and use them without restrictions.

Sure, if you want to make a concert and charge for tickets, you might do the choreography part more professionally and use fancy projection technology, so people actually have a reason to pay for those tickets. Otherwise people can just compile a concert themselves and project it in their homes. I did just that for my family to explain the phenomenon to them.

As for your last paragraph, I don't think I can convince you something fictional is not "fake". You shouldn't expect animation to look real because that is not the point of animation. As for lacking emotion, I bet you have not heard songs that try to do just that instead of being gimmicky. Try this: https://www.youtube.com/watch?v=3BFvN-idN1s This was made by just two people. One did the music and lyrics, the other the illustration and video.

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.
