From Nowtro Software:
Nowtro Jukebox enables your party guests to choose which music from your MP3 collection they'd like to hear without the chaos associated with giving everyone unrestricted access to your CD player or iPod. It functions just like a true jukebox, allowing users to browse artists alphabetically and make requests by typing in the number of their selection on a stylish interface reminiscent of the Nintendo/DOS era. Each guest can choose their own unique five-digit "User ID", which they use to make requests. Based on the size of your gathering, you, the administrator, can set the number of credits each user receives, and as well as the "refill time" - the amount of time it takes for a user with zero credits to acquire the maximum number of credits. When a user runs out of credits, they will be "locked out" of the request screen until their credits are automatically "refilled". Not having a party? You can easily turn the "Require ID" option off for unlimited credits without the use of IDs.
Version 2.04 adds Auto-Start feature, updates Controls Diagram for desktop computers.
