AKA, Jonathan Coulton, mentioned way back in one of my first posts, is a singer/songwriter, mostly of humorous music. He's most famous among my co-workers for "Code Monkey", but he's also semi-famous for the song mentioned in that earlier post, "Still Alive". He's got some seriously hilarious stuff, though. He's a pretty good live singer too, which makes sense given that he used to be a Whiffenpoof (you'll forgive them the girly name, I hope).

"RE: Your Brains" is all about a group of zombies trying to convince holdouts in a shopping mall to let them in. It's really funny with audience participation.

"First of May" is a song some might consider close to some of Tenacious D's stuff (it's not rock, but it's definitely vulgar).

"Ikea" is a song about, you guessed it, Ikea. It's also a song that uses the not-quite-rhyme of "Norsemen" with "[Di]vorced men".
