The right side as you enter the 'player' where you can listen random 4 complete songs ... just never know what will. This section Shake = Shuffle.
On the left side you enter the 'puzzle' mode. You take the pieces and drag them to the bottom to put together a musical timeline. To create another and erase what you did just a 'shake' the device.
The puzzle can reach a maximum duration of 40 mins (the approximate length of a vinyl) so 'infinite' allows you to build any number of LP's from the material.
