Portable Juke Boxes

For the many travelers out there I believe there should be such an item similar to a boombox or a portable jukebox. It would work extremely similar to the normal jukebox however with the difference as such you could keep it in your inventory or maybe add it to your avatar, and place a disc inside it for it to start playing wherever you go. This way while you travel you can have your favorite discs playing as you walk and you don't need to wait till you get where you're going to have to listen to your music.
