The user can assign a predefined color to a given play list. Shake the cube to activate it: the four color side lights will come on, indicating the cube is ready for interaction. A play list can be selected by placing the color side of the desired play list upwards.
Rotating the top button allows scrolling through the songs in the play list. Shaking the cube activates the shuffle mode. Placing the cube with the top button facing downwards and pressing will "switch off" the device.
