Abstract

The present invention is a computer system adapted to play audio files. The computer system includes a central processing unit, a storage unit, a first operating system, an interfacing unit, and a second operating system. The first operating system can control at least the CPU. The interface unit can interface with an external digital media device that may store a plurality of compressed audio files. The second operating system is capable of controlling the computer system operating in an audio playback mode. The power of the computer system is turned on and the computer system plays the plurality of compressed audio files in the audio playback mode when the external digital media device is in communication with the interface unit.
