The personalized content system of the system combines a summary music identification value creation and identification algorithm that represents a mathematical summary music identification of a song, an audio file, or other relational music criteria and data (e.g title, artist, genre, style, beats per minute, etc.) or any combination thereof. The derived value represents the musical taste or style attributes of a song or style. The user can control the system by issuing one of a plurality of commands comprising artist command, song/title command, genre command, and album/filtered list command. These commands then lead to command trees that may be used in a voice controlled system, for example.
