A method, system and user interface are provided for building and programming an online media (radio or TV) station based on collaboration by the station's users. The method includes creating an initial playlist for an online media station; creating a set of recommended media content items distinct from the initial playlist; aggregating user input regarding the recommended media content items; and generating a new playlist in accordance with the aggregated input. The user input regarding a given item of media content may include a positive vote or a negative vote. Each item added to the playlist after the initial playlist is voted on by the users, so that each item of the new playlist has an aggregated positive vote greater than a predetermined vote threshold.
