System Overview

Introduction

The field that we decided to do it in, the choice we made, was music. Now, why music? Well, we love music. We have a created a major breakthrough in the music and technology. Introducing, miPod. What is miPod? miPod is a WAV music player that only supports one file format, doesn't fit in your pocket and holds up to 64 songs...maybe. The coolest thing about miPod is it's a family sharing device so instead of everyone having their own device we decided to modernize by allowing one device to hold up to 64 different people.
