Jonathan Coulton (born December 1, 1970) is an American singer-songwriter, whose claim to fame was his use of the Internet to distribute his music.
In 2005, he quit his job as a software writer to embark on a project he named "Thing a Week", for which he released a song every Friday for an entire year. This project was a massive success, and Coulton is now regarded an "Internet super-star". He now makes his living as a musician.
Famous for his music containing themes of geek culture, he has been featured in two video games by Valve, the first being Portal, for which he wrote the credits song, "Still Alive", sung by Ellen McLain. On The Orange Box Original Soundtrack, a version of the song sung by him is featured. The other is one of his earlier songs, "Re: Your Brains", which was included, along with "Still Alive", in a jukebox in Left 4 Dead 2. This song is framed as a memo sent by an infected zombie horde representative to his old co-worker trapped inside a mall indefinitely.
