I just read in John Buckman’s Magnatune blog his post about the API they are exposing via XML. Magnatune isn’t telling people what to do per se but exposing their information via XML and letting people’s imagination run free. You could use this to make an ongoing Magnatune jukebox that allows you to randomly play their songs while providing a button that allows you to buy the album if you like what you are hearing. That’s quite cool. When Amazon exposed their API, it provided for some interesting stuff and I would expect the same from this experiment.
