All videos MUST be sung by one of the vocaloids ! Utau’s are only accepted if it is a duet with a vocaloid.
English vocaloids are okay.
At the moment nico singers are not allowed they will be in the future though so watch out :)

When submitting a post make sure you include the vocaloid name, Japanese title, English title and nico link.

If you don’t know the English title then it’s okay to have only the Japanese title (or the other way around).
You MUST include a nico link!

If the song is made by a youtube user or if it is from a CD it’s okay to not include the nico link.
