User blog comment:Dizzyzebra/Who's the Most Popular Engloid on Youtube?/@comment-25577599-20150221233033

Well, YOHIOloid's only explanation  (that I can think of), is that he was massively hyped prior to his release. He was made with the anime style in mind, and on top of that he was born from a contest, with the artist being fairly well known. It's understandable that he would have the most, especially since he's Japanese-English bilingual. ..Even though neither one of those languages are that great when sung by the VOCALOID. >_>
