I'm working for a Vocaloid rhythm game, but sorry I can't describe about it now.
The things I really need is 300 Vocaloid Songs.
I'm fine with cover songs.
Now I'm having about 150 songs so I need 150 more (it's the half!).
You can write as many as you want
Just write the title. It's fine if you don't write the vocalist and the composer. I would just go Google it.
Note: Sorry for my bad English :p
