I checked out a bunch of his stuff on you tube. I'm pretty impressed so far. His music isn't terribly original, but it's certainly good, and his lyrics are great. He reminds me a bit of Barenaked Ladies, but they kind of always seem to be either really serious or really silly, and Coulton seems to find a nice middle ground sometimes that i like.
I said it before, and I'll say it again, I love Jonathan Coultan's music. Code Monkey is one of my favorite songs by him, but the acoustic version you got there just sounds weird to me.
The Future Soon is another one of my favorite songs.
