Over the weekend I saw this post by Paul Lamere about a Python script by Tristan Jehan called the Swinger that uses the Echo Nest Remix API to alter the beat of a recording. It works by alternately stretching and shortening beats to create a pseudo-swing effect. It’s really rather addictive once you’ve started:

Hungry Like the Wolf

Come Out and Play

Take Me I’m Yours

The Bad Touch

Coconut

Video Killed the Radio Star

Barbie Girl

Hollaback Girl
