Data streams are generally selected according to user preferences and transmitted to the user in general alignment with expressed preferences of the user. Such data streams may be music, including music videos. Users may indicate their general or specific preferences with regards to song, artists, or albums. Any other aspects or factors that might affect the user's preferences can be taken into account. A playlist is created that combines all of these factors. The playlist then serves as the basis for feeding the data streams to the user. Each user is able to express his or her own preferences and receive music corresponding to those preferences on an on-going basis.
