Have you heard of him? I hadn't either, until I saw a link on another page (I forget which).
I love acoustic guitar, and funny lyrics, and hippie-ish singers. That's why I am now a fan of one Jonathan Coulton.
Here's a link to his music page. I especially recommend Baby Got Back and Re: Your Brains. But if you scroll down, you're sure to find a title that piques your interest.
