"Video game composer" must be a weird job, but Jonathan Coulton pulled it off with aplomb with his songs in the video game "Portal," which is maybe the coolest and most innovative video game ever. Fuse caught up with Coulton at the PAX East video game convention.

"Gladys was such a fantastic character that it was easy to write a song for her to sing." Gladys is an "evil, demented supercomputer."

So how much does this singer/songwriter with no label make per year? You'll have to watch the video above to learn the exact amount, but let's say it's more than $400,000/year. Wow.
