1. Digital jukebox device, comprising a central processing unit controlling, using a multitask operating system, a display, a touch screen, at least one memory location, and a communication system for enabling the jukebox device to communicate with a network, said network at least capable of providing audio information distribution, said operating system comprising an interpreter for interpreting touches of an operator to the touch screen and for allowing the operator to access an operating system module, said module usable for adding credits to a credit reserve, the credit reserve being designated for use by a manager, different from the operator, of the audiovisual reproduction system, with one credit corresponding to the fee necessary to select a song, wherein a free play reserve file on the memory is readable/writeable to store the number of credits added by the operator as a credit reserve, said free play reserve file being separate from a general reserve file used to store credits based on user payments, said number of credits in said free play reserve file being decremented each time the manager redeems a credit and incremented at least each time the operator supplies one or more credits and further reserving said credits for protected use by said manager, said interpreter being adapted for further interpreting: a first button touch in a first area of the touch screen as a request for adding one credit to the number of credits reserved in said free play reserve file, and a second button touch in a second area of the touch screen as a request for redeeming one credit from the number of credits in said free play reserve file and removing said redeemed credit from the number of credits in said free play reserve file only if the credit reserve is not empty, said central processing unit operable to cause said display to display at least a first screen including at least the first button for the operator, and at least a second screen including at least the second button for the manager, wherein said first screen and said second screen further include an interface, being automatically displayable in at least one of the first screen and second screen when one of said specific buttons is used, said interface protecting said free play reserve file and requiring a first code for using said first button to function as a request for adding one credit to the credit reserve in said free play reserve file when this first button is touched, said interface requiring a second code for using said second button to function as a request for redeeming one credit from the number of credits in said free play reserve file and removing one credit from the credit reserve in said free play reserve file when this second button is touched, wherein said first code must be entered each time a credit is added to said free play reserve file and said second code must be entered each time a credit from said free play reserve file is redeemed.
