I would come up with our own characters and songs... Vocaloids aren't cheap but they do have a license and all. Though a fan game would be not ness. a violation of the license, I honestly don't see the advantage of using Vocaloid charaters at least.

The songs should be fine providing their your own and your not declaring its a Vocaloid game. In short, if you use them as vocal instruments and not as "Hatsune Miku" etc..
