Our Song-Request Contest Has a Winner

We recently ran a contest in which you were invited to submit requests for a custom-written song by Jonathan Mann, who writes and posts a song a day here. He first came to our attention because of his song “Hey, Paul Krugman.”
As it turns out, Mann has already written songs on a lot of topics that you requested, including zombie banks, swine flu, and endangered newspapers.
What he hadn’t written yet, however, was a Freakonomics theme song. That’s the request Mann decided to fulfill. It came from a reader named Spencer, who’ll get his choice of Freakonomics schwag for winning the contest.
So here it is, the theme song we never knew we needed but now wouldn’t want to live without. Thanks to all for participating, and especially to Jonathan Mann for lending his talents to our cause:
