It's rather folksy, but he's certainly very talented. That was a funny song, and I can't believe someone spent all that time animating that video in such detail like that. It must have taken a long time to do that.
I am not passionate about music as much as I used to be however Coulton is everything I like about a lot of music, it is a lot of fun. Plus he gets it about copyright, second best reason ever to like an artist.
There's a guy who does World of Warcraft video's using mostly Coulton music, and some other Creative Commons Licensed music.
"Code Monkey" - For the lovelorn coder.
"Re: Your Brains" - Ever worked in an office with someone who is an asshole? This kicks it up a notch.
"Skullcrusher Mountain" - Not the most dysfunctional love song I've ever heard, but... o.k., maybe it is.
"Baby Got Back" - I love the original, as I am a fan of the human posterior. This version is very wrong, and funny in its wrongness.
I'm off to see JoCo in concert soon. I'll report back, and make more listening suggestions.
