To replace mp3 you need to win on at least one of these fronts: * licensing/royalties * quality per bit * power consumption to decode The article addresses none of these, but instead talks about being able to remix an song to suit your tastes because all of the instruments are on different tracks. This is just silly. Rounded to one percent, no one wants to do this to their music. Add to that, it isn't really possible because in any modern musical production there is audio processing that happens to groups of tracks on the way to a final mix and then more processing on all of the tracks combined. The final product is not a linear combination of the inputs. A poorly thought out gimmicky feature is not going to replace mp3. Oh, the labels will have to support it since it will require completely new production techniques and if the cost doesn't cause them an aneurism then the idea that you can go in and rip out a drum line to sample will.
