Abstract: Systems and methods for providing a multi-tier enterprise level application. In particular, the present invention relates to systems and methods for providing an architecture and interface for delivering customizable music and advertisements to remote retail locations. A client player computer device is located at the retail location and a server system is located at a remote location. The server system selectively provides broadcast information when an active contract, an active advertisement, and an active schedule are available. The client player computer device establishes a contact with a server at a predetermined time or upon request by the server or another source. The client player computer device executes a broadcast or program schedule that includes music content and advertisements, wherein the advertisements have been purchased as blocks of time by entities and are scheduled to be broadcast at particular times.
