The Swinger hacks any song to... swing

Here's an amazing little bit of code which hacker (and alumnus of MIT's Hyperinstruments Group) Tristan Jehan put together at the recent Music Hack Day in San Francisco. The premise of the Python program is simple: take any song and make it swing. The code accomplishes this task by taking each measure and time-stretching the first half of each beat while time-shrinking the second half. Then blammo -- it swings. Honestly, it's best you just listen to the results yourself... you'll never hear "Enter Sandman" the same way again. Check out a few examples after the break.

Enter Sandman -- Metallica

Around the World -- Daft Punk

Money For Nothing -- Dire Straits
