Last week was Music Hackday in San Francisco, actually a whole weekend in which hackers convened to conceptualize, build, and present the next generation(s) of music applications. One of the best presentations was Tristan Jehan‘s Swinger, a python code that takes any song and puts it into swing mode. Click here to listen to fresh jive versions of classics like “Money for Nothing,” “Sweet Child of Mine,” and “White Rabbit.”
