MusicMagic, a chain of audio rental stores, is experimenting with adding a new Web-based service to its store (similar to www.amazonmusic.com) that would allow a monthly or annually paid subscription. The online services permit customers to choose a list of songs and hear the songs through their laptop or mobile unlimited times until the subscription ends. Your organization was selected for developing and maintaining the web-based service and you have successfully developed the services.
