"Gangnam Style" Psy, who has over a billion views on YouTube, was surprisingly not revealed as the most popular Hallyu star on YouTube.

Today they revealed the YouTube statistics and showed the 15 most viewed videos that popped up when using the keyword 'K-Pop'.

4 of the videos were related to Psy, 5 were related to Big Bang, 3 for Girls' Generation and more. For music video views, Psy placed first with Girls' Generation taking second and third place.

One of the researchers stated, "Having the most views does not make them the most popular." They continued by saying that if the video was created for advertisement purposes, the positive feedback from the audience is supposed to part of the plan. They stated that the number of 'likes' would provide a more accurate feedback on which videos were in fact 'popular'.

When looking at just comments, Big Bang ranked first. However, Girls' Generation, who received many more comments, actually had more 'dislikes'.

Although Psy may seem like the top Hallyu star with his music video views, when looking at it in terms of 'likes' and comments, his has stopped at around 87%.

The online researchers agreed that when calculating for the most popular, it is important to not only look at the views but also the comments and likes in order for a more accurate answer.
