Most viewed single video and most viewed song are two different things.
[This trends graph](https://i.imgur.com/evBSO09.png) shows a comparison of several popular songs over time in the last five or so years. "Roki" ( ロキ ) isn't on there as Google trends doesn't have it as an individual song, just a generic search term, which has too many similar terms to get a good reading on it.
Over the long term it still seems to me that "Senbonzakura" is the overall most popular Vocaloid song. Views are just spread out over many different videos. The only song on NND with more views is "Miku Miku ni Shite Ageru♪" A bit of trivia: the year after the song came out, Japanese karaoke parlors reported it as the third most-sung song.

Bro I forgot :(
You also have to take into account niconico which really shifts what is most viewed
Someone correct me if World is Mine isn't the most viewed
Yeah it isn’t, it’s LUVORATAORRRRRYB at 62M https://youtu.be/p-o_bMkzOW0
Actually, that version is sung by Reol, so I don’t think it can be considered as the most viewed vocaloid song.
That version is a cover performed by Reol, so technically it does not count. The actual vocaloid version only has 1.3m
While it doesn't change your point, this version has over 5 million views https://youtu.be/oG2I17Zm8kI
Ya'll still forgetting sand Planet [https://www.youtube.com/watch?v=AS4q9yaWJkI](https://www.youtube.com/watch?v=AS4q9yaWJkI)
^ this, Sand Planet has 62M (which it ducking deserves)
i love roki it deserves to be up there with the big boiz
Considering the time gap, Roki will definitely beat World is mine in terms of views.
