So, this is a blog that I run! I go into the Vocaloid tag and try to source any of the unsourced art. I'd appreciate it if you followed it (If you have a tumblr) so people will know to reblog the art with the correct sources.
a website that started up quite awhile ago, it's trying to become a Western hub for Vocaloid/UTAU music. It's not to bad, a pretty decent spot for find songs by engloids. If you want to pick up something without trying to find it on youtube try it.
