An apparatus, method and computer program product are provided which establishes a user interface for portable media players in which a user can mix, shuffle, randomize, or otherwise alter the selection and/or ordering of media items stored within and/or played by the portable media player by simply shaking the portable media player in a characteristic manner. It is a common human metaphor to mix the contents of a physical object, like a bottle of salad dressing or a carton of orange juice, by physically shaking the object. The various embodiments leverage this common and well known human activity by enabling a user to "mix" media items through a characteristic shaking motion as a type of user interface. This capability enables a user to have a portable media player automatically shuffle the order of songs stored within a play arrangement by shaking the portable media player using a characteristic shaking motion. The portable media player includes a motion sensor coupled to a processor, a control program to monitor signals output from the motion sensor and to interpret characteristic shaking motions for causing one or more changes to be made to a current play arrangement.
