We are fortunate to have virtually our entire music collection with us, at slightly reduced fidelity, in the form of our creative labs 40G jukebox player.  It was quite a lot of work to set up (there must be a better way for people with large cd collections), but it's great to have everything from the Indigo Girls to Veronique Gens to Deep Forest, John Coltraine, and Bill Evans, all at your fingertips, where-ever you may be.
