Ello! I just found a site with a bunch of vocal samples. Thought id' let you in on it in case you didn't know about it already. http://www.looperman.com Looks like all of it's for free, just need to register to download. And you might need to refer to the artist if you make something witch you publish. I've been having a hard time looking for vocals before but this site actually have a lot of useful stuff imo. (oh, and there's drum loops and other samples over there as well but the vocals where the stuff that seamed the most rare to me). Ait, hope I helped someone out!
