1. A system for generating a playlist of media objects, comprising using a local client computer to perform steps including: (a) a step for retrieving a subset of coordinate vectors corresponding to locally available media objects from a remote server computer; (b) a step for selecting a media object from the locally available media objects, adding the selected object to a playlist, and setting a corresponding one of the coordinate vectors as a current point; (c) a step for searching the subset of coordinate vectors to locate a coordinate vector having a closest distance to the current point, adding the media object corresponding to the located coordinate vector as a next media object in the playlist, and setting a point corresponding to the located coordinate vector as the current point; and (d) a step for repeating step (c) until the playlist reaches a desired length.
