Bangarang Boomerang is Paul Lamere’s latest creation from the Echo Nest. In his blog post, Paul describes it as: “My latest music hack is Bangarang Boomerang. It is a web app (runs in Chrome or the latest Safari), that lets you ‘drive’ the Skrillex song. You can freeze-frame the song on a beat, you can make the song go backwards beat by beat, you can advance through the song at double time, or triple time, and set bookmarks to let you easily jump to different sections of the song. It is a rather fun app that lets you feel like a musician, even if you have very little musical talent. ”
