Python script turns any song into a swing number

dj BC sez, "Tristan Jehan from M.I.T. has created a unique and simple music hack, which my buddy Solcofn stumbled across on Paul Lamere's excellent 'Music Machinery' blog."
White Rabbit - The Swing Version by plamere

One of my favorite hacks at last weekend's Music Hack Day is Tristan's Swinger. The Swinger is a bit of python code that takes any song and makes it swing. It does this be taking each beat and time-stretching the first half of each beat while time-shrinking the second half. It has quite a magical effect.

Check out the examples from the likes of The Police, Daft Punk, Metallica, and Prince.
