"Apple, Google and Amazon are all reportedly in discussions with big labels to provide a cloud music service. ... The labels, say our source, are demanding that a user can only stream music that is watermarked to their username. Change the username, or try to stream music that you’ve ripped from a CD, and those songs won’t play." It's a stupid idea to propose that you wouldn't be able to access music you put into the cloud that didn't have your personal watermark in it. Let's assume Johnny has an all-legal music collection dating back 10 years - consisting of iTunes (watermarked) MP3s, Amazon (non watermarked) MP3s and a ton of self-ripped MP3s from his old CD collection (non watermarked). There is no way Apple, Amazon or anyone else would find success and adoption in a system that would only let him play the watermarked files purchased from iTunes but deny him playing the rest of his legal collection. Anyone building such a system, regardless of the music industries demands, needs to find a new product manager.
