A list of every single nico nico singer and their mylists/youtube link.
(Based on quality of voice?)
Male / Female.
They do have a page, but this just links to their mylist/youtube list so that you can look at all your songs yourself. simply the song list.
For the critical , something else? a comment : Dasoku's voice strong & deep. Maybe collapsable table/spoiler or something.
Maybe a mouse's choice for my favorite nico nico singers and notes on qualities. in a different page.
A page full of the full songs (Miku, Len, Rin, Kaito, Meiko, Gumi, etc.), and that links to the pages with the other songs.
