I figured the next generation home audio source after the death of the CD would've been a hard drive in a box with a usb slot. Say you buy a source with a 20GB hard drive and upload your music via a jump drive, or even better, your laptop/desktop, iphone, whathave you. With a computer, you can access your home stereo HD source and arrange your files however your want them.

Why isn't this available? The technology is there, we just need a few good companies to step up and put it into production.
