A method of operating an entertainment system in a vehicle, said method comprising the computer-implemented steps of: accessing a source of audio/video content (14, 22, 24), the source being capable of providing a plurality of media items; analyzing the media items to thereby determine a corresponding classification for each of the media items; providing a visual representation of each of the classifications on a display of the entertainment system; sensing one of the classifications being selected by a user; and in response to the sensing, at least one of: playing one of the media items corresponding to the selected classification; and offering the user a choice among a plurality of the media items corresponding to the selected classification, wherein the sensing step includes sensing a plurality of the classifications being selected by a user in a sequential order, and, in response to the sensing, ones of the media items having the selected classifications are played, the media items being played in an order of their classifications in the sequential order, comprising the further steps of: providing a marker on the representation of the classification of a currently-played media item; detecting the user moving the marker from a first said selected classification to a second said selected classification; and in response to the detecting, switching from playing one of the media items having the first said selected classification to one of the media items having the second said selected classification. accessing a source of audio/video content (14, 22, 24), the source being capable of providing a plurality of media items; analyzing the media items to thereby determine a corresponding classification for each of the media items; providing a visual representation of each of the classifications on a display of the entertainment system; sensing one of the classifications being selected by a user; and in response to the sensing, at least one of: playing one of the media items corresponding to the selected classification; and offering the user a choice among a plurality of the media items corresponding to the selected classification, playing one of the media items corresponding to the selected classification; and offering the user a choice among a plurality of the media items corresponding to the selected classification, wherein the sensing step includes sensing a plurality of the classifications being selected by a user in a sequential order, and, in response to the sensing, ones of the media items having the selected classifications are played, the media items being played in an order of their classifications in the sequential order, comprising the further steps of: providing a marker on the representation of the classification of a currently-played media item; detecting the user moving the marker from a first said selected classification to a second said selected classification; and in response to the detecting, switching from playing one of the media items having the first said selected classification to one of the media items having the second said selected classification. providing a marker on the representation of the classification of a currently-played media item; detecting the user moving the marker from a first said selected classification to a second said selected classification; and in response to the detecting, switching from playing one of the media items having the first said selected classification to one of the media items having the second said selected classification.
