Turning a NES controller into a mp3 player could look like a very difficult task but you know modders, they just like to take this kind of challenges.

A guy turned his cheap usb mp3 player into the NESamp. You can control the songs with the D-pad, play them by pushing start and even control the volume with the A and B buttons. You can follow his example and go Nintendo Style, how about playing the Ocarina of Time soundtrack with this player? That would be pretty cool.
