Here's a nice piece of software with a DJ scratching it up for a product demo. What more does one need, sometimes?

From the Rane website:

"Scratch LIVE is the ultimate software and hardware solution for bridging the analog world of vinyl and the digital world of computer audio files. Using regular turntables or CD players, you can scratch and mix files from your Mac or Windows computer's CD or hard drive, add in a live mic input for scratching, and even bypass to standard vinyl if you wish. Scratch LIVE is the complete digital solution for the vinyl junkie -- take your entire collection wherever you go and leave your precious vinyl at home!"
